Fill in the Math object eagerly, to avoid its structure changing during
execution. There are lots of ways to skin this cat; this one seemed
easiest, and justified given the relative hotness of math operations.

20% speedup on DSP-filtrr tests, small speedups on a few Kraken tests.

This turns new String(), String(), String.prototype.valueOf(), and
String.prototype.toString() into intrinsics. It gives the DFG the ability to handle
conversions from StringObject to JSString and vice-versa, and also gives it the
ability to handle cases where a variable may be either a StringObject or a JSString.
To do this, I added StringObject to value profiling (and removed the stale
distinction between Myarguments and Foreignarguments). I also cleaned up ToPrimitive
handling, using some of the new functionality but also taking advantage of the
existence of Identity(String:@a).
        
This is a 2% SunSpider speed-up. Also there are some speed-ups on V8v7 and Kraken.
On microbenchmarks that stress new String() this is a 14x speed-up.

RegExp.prototype.exec & RegExp.prototype.test can both be used to test a regular
expression for a match against a string - however exec is more expensive, since
it allocates a matches array object. In cases where the result is consumed in a
boolean context the allocation of the matches array can be trivially elided.

For example:
    function f()
    {
        for (i =0; i < 10000000; ++i)
            if(!/a/.exec("a"))
                err = true;
    }

This is a 2.5x speedup on this example microbenchmark loop.

In a more advanced form of this optimization, we may be able to avoid allocating
the array where access to the array can be observed.

Adds Math.min, Math.max, and Math.sqrt intrinsics. Adds support for
a function to have an intrinsic but not a thunk generator. This is
a 7% speed-up on access-nbody, and neutral elsewhere, mainly because
we're still not DFG compiling the bulk of the hot code in Kraken audio
benchmarks.

This adds the ability to track intrinsic functions throughout the
host function infrastructure, so that the DFG can easily query
whether or not a call's target is intrinsic, and if so, which
intrinsic it is.
        
On top of this, it adds Math.abs intrinsics to DFG. Call(Math.abs)
is transformed into ValueToNumber<-ArithAbs nodes. These nodes
then get optimized using the usual tricks.
        
Also had to make a completely unrelated change to
DateInstanceCache.h in order to fix a preexisting alphabetical
sorting problem in JSGlobalData.h
        
This results in a big win in imaging-gaussian-blur: 61% faster
than before. The net win on Kraken is around 13%.

        Add fast paths for Math.pow and Math.sqrt
        https://bugs.webkit.org/show_bug.cgi?id=38294

        Add specialized thunks for Math.pow and Math.sqrt.
        This requires adding a sqrtDouble function to the MacroAssembler
        and sqrtsd to the x86 assembler.

        Math.pow is slightly more complicated, in that we have
        to implement exponentiation ourselves rather than relying
        on hardware support.  The inline exponentiation is restricted
        to positive integer exponents on a numeric base.  Exponentiation
        is finally performed through the "Exponentiation by Squaring"

        Need to support more efficient dispatch of lightweight builtins
        https://bugs.webkit.org/show_bug.cgi?id=38155

        The problem with calling lightweight builtins is that marshalling
        the call from the nitro calling convention to the system calling
        convention is very expensive relative to the cost of the actually
        evaluating the function.  To work around this problem this patch
        adds the ability to define a custom thunk for a builtin.

        This allows us to use high performance custom implementations of
        the common and sensible versions of simple builtins.  This patch
        includes a simple (use of which is currently hardcoded) thunk for
        charCodeAt.

        This adds a JSInterfaceJIT subclass called SpecializedThunkJIT
        that has helper functions to remove (or at least reduce) the need
        to have separate thunk implementations for each JSValue encoding.

        Make the lookup table generator include an explicit cast to expected
        type of the function.  We do this because otherwise the blind intptr_t
        cast that is subsequently applied allows incorrectly typed functions
        to be inserted into the table, where they will only fail at runtime.
        This change makes such errors produce a compile time failure.

        <rdar://problem/6331749> Provide a mechanism to disable perfect hashing in the DOM at build time

        Reviewed by Darin Adler.

        Initial patch by Yosen Lin.  Adapted for ToT WebKit by David Kilzer.

        Added back the code that generates a "compact" hash (instead of a
        perfect hash) as a build-time option using the
        ENABLE(PERFECT_HASH_SIZE) macro as defined in Lookup.h.

JavaScriptCore:

        * create_hash_table: Rename variables to differentiate perfect hash
        values from compact hash values.  Added back code to compute compact
        hash tables.  Generate both hash table sizes and emit
        conditionalized code based on ENABLE(PERFECT_HASH_SIZE).
        * runtime/Lookup.cpp:
        (JSC::HashTable::createTable): Added version of createTable() for
        use with compact hash tables.
        (JSC::HashTable::deleteTable): Updated to work with compact hash
        tables.
        * runtime/Lookup.h: Defined ENABLE(PERFECT_HASH_SIZE) macro here.
        (JSC::HashEntry::initialize): Set m_next to zero when using compact
        hash tables.
        (JSC::HashEntry::setNext): Added for compact hash tables.
        (JSC::HashEntry::next): Added for compact hash tables.
        (JSC::HashTable::entry): Added version of entry() for use with
        compact hash tables.
        * runtime/Structure.cpp:
        (JSC::Structure::getEnumerablePropertyNames): Updated to work with
        compact hash tables.

WebCore:

        * bindings/scripts/CodeGeneratorJS.pm:
        (GenerateImplementation): Compute the number of elements that will
        be stored in each hash table and pass it to GenerateHashTable().
        (GenerateHashTable): Added new second parameter representing the
        number of elements to store in the compact hash table.  Added back
        code to compute compact hash tables.  Generate both hash table sizes
        and emit conditionalized code based on ENABLE(PERFECT_HASH_SIZE).

        Bug 20704: Replace the KJS namespace
        <https://bugs.webkit.org/show_bug.cgi?id=20704>

        Rename the KJS namespace to JSC. There are still some uses of KJS in
        preprocessor macros and comments, but these will also be changed some
        time in the near future. There are also some uses in the names of JNI
        functions, but I will check if these are safe to change as well.

        Proxy server issue in Sunday's Nightly

        Changed ClassInfo objects for built-in objects to hold a getter function returning
        a per-thread instance. This makes it safe to share these ClassInfo objects between threads -
        and these are the only ones that need to be shared.

        Convert JavaScript internal function objects to use one class per
        function.  This avoids a switch statement inside what used to be
        the shared function classes and will allow Shark to better analyze
        the code.

        To make this switch, the value property of the HashEntry was changed
        to a union of an intptr_t (which is used to continue handle valueGetters)
        and function pointer which points to a static constructor for the
        individual new function objects.

        SunSpider claims this is a 0.5% speedup.

        Convert JavaScript internal function objects to use one class per
        function.  This avoids a switch statement inside what used to be
        the shared function classes and will allow Shark to better analyze
        the code.

        To make this switch, the value property of the HashEntry was changed
        to a union of an intptr_t (which is used to continue handle valueGetters)
        and function pointer which points to a static constructor for the
        individual new function objects.

        SunSpider claims this is a 0.5% speedup.

        - On the WebCore side, I updated CodeGeneratorJS.pm to generate the
          new classes and hand updated the remain non-generated (groan) classes.

        Seems to give 0.7% SunSpider speedup.

        * kjs/lookup.cpp:
        (KJS::keysMatch): Took out unneeded typecast.
        (KJS::findEntry): Updated to expect table type 3 -- changed the printf to a plain old assert.
        Replaced the modulus with a bit mask.
        (KJS::Lookup::findEntry): Get the hash directly, since we know identifiers already have computed
        their hash -- saves a branch.
        (KJS::Lookup::find): Ditto.
        * kjs/lookup.h: Changed attr from 2-byte value to one-byte value. Replaced hashSize with hashSizeMask.
