• VM/RegisterFile.h: (KJS::RegisterFile::RegisterFile): Removed an ASSERT().
• kjs/JSArray.cpp: (KJS::JSArray::putSlowCase): Changed to use tryFastRealloc(). (KJS::JSArray::increaseVectorLength): Ditto.
• kjs/ustring.cpp: (KJS::allocChars): Changed to use tryFastMalloc(). (KJS::reallocChars): Changed to use tryFastRealloc().
• wtf/FastMalloc.cpp: (WTF::fastZeroedMalloc): Removed null checking of fastMalloc()'s result and removed extra call to InvokeNewHook(). (WTF::tryFastZeroedMalloc): Added. Uses tryFastMalloc(). (WTF::tryFastMalloc): Renamed fastMalloc() to this. (WTF::fastMalloc): Added. This version abort()s if allocation fails. (WTF::tryFastCalloc): Renamed fastCalloc() to this. (WTF::fastCalloc): Added. This version abort()s if allocation fails. (WTF::tryFastRealloc): Renamed fastRealloc() to this. (WTF::fastRealloc): Added. This version abort()s if allocation fails. (WTF::do_malloc): Made this a function template. When the abortOnFailure template parameter is set, the function abort()s on failure to allocate. Otherwise, it sets errno to ENOMEM and returns zero. (WTF::TCMallocStats::fastMalloc): Defined to abort() on failure. (WTF::TCMallocStats::tryFastMalloc): Added. Does not abort() on failure. (WTF::TCMallocStats::fastCalloc): Defined to abort() on failure. (WTF::TCMallocStats::tryFastCalloc): Added. Does not abort() on failure. (WTF::TCMallocStats::fastRealloc): Defined to abort() on failure. (WTF::TCMallocStats::tryFastRealloc): Added. Does not abort() on failure.
