Reviewed by Cameron Zwarich. - speed up transitions that resize the property storage a fair bit ~3% speedup on v8 RayTrace benchmark, ~1% on DeltaBlue * VM/CTI.cpp: (JSC::resizePropertyStorage): renamed from transitionObject, and reduced to just resize the object's property storage with one inline call. (JSC::CTI::privateCompilePutByIdTransition): Use a separate function for property storage resize, but still do all the rest of the work in assembly in that case, and pass the known compile-time constants of old and new size rather than structureIDs, saving a bunch of redundant memory access. * kjs/JSObject.cpp: (JSC::JSObject::allocatePropertyStorage): Just call the inline version. * kjs/JSObject.h: (JSC::JSObject::allocatePropertyStorageInline): Inline version of allocatePropertyStorage * masm/X86Assembler.h: (JSC::X86Assembler::): (JSC::X86Assembler::pushl_i32): Add code to assmeble push of a constant; code originally by Cameron Zwarich. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@37653 268f45cc-cd09-0410-ab3c-d52691b4dbfc
