        ExecutableAllocatorSymbian appears to have buggy ARM version check
        https://bugs.webkit.org/show_bug.cgi?id=33138
        
        * wtf/Platform.h:
        Rename all macros related to detection of particular CPUs or
        classes of CPUs to CPU(), reorganize and document them.

        All remaining changes are adapting to the renames, plus fixing the
        second bug cited above.
