Reviewed by Mark Lam.

Source/JavaScriptCore:

This is needed to enable the DFG. MSVC does no longer support inline assembly
for 64-bit, which means we have to put the code in an asm file.

• assembler/MacroAssemblerX86Common.cpp:

(JSC::booleanTrueForAvoidingNoReturnDeclaration): Deleted.

• jit/JITStubsMSVC64.asm:

Source/WTF:

Enable masm probe and DFG.

• wtf/Platform.h:
