Really "fix" CTI mode on windows 2k3.
Reviewed my Maciej Stachowiak This adds new methods fastMallocExecutable and fastFreeExecutable to wrap allocation for cti code. This still just makes fastMalloc return executable memory all the time, which will be fixed in a later patch. However in windows debug builds all executable allocations will be allocated on separate executable pages, which should resolve any remaining 2k3 issues. Conveniently the 2k3 bot will now also fail if there are any fastFree vs. fastFreeExecutable errors. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@37804 268f45cc-cd09-0410-ab3c-d52691b4dbfc
