        - assorted optimizations to === and !== operators
        (work towards <https://bugs.webkit.org/show_bug.cgi?id=20820>)
        
        2.5% speedup on earley-boyer test

        * VM/Machine.cpp:
        (JSC::Machine::cti_op_stricteq): Use inline version of
        strictEqualSlowCase; remove unneeded exception check.
        (JSC::Machine::cti_op_nstricteq): ditto
        * kjs/operations.cpp:
        (JSC::strictEqual): Use strictEqualSlowCaseInline
        (JSC::strictEqualSlowCase): ditto
        * kjs/operations.h:
        (JSC::strictEqualSlowCaseInline): Version of strictEqualSlowCase that can be inlined,
        since the extra function call indirection is a lose for CTI.
