Reviewed by Yusuke Suzuki.

Switched register mapping on Windows to match the other x86-64 platforms
Added SystemV ABI function annotation to C++ entrypoints for JS LLInt
Disabed WebAssembly LLInt, as it doesn't work without JIT anyway, so we
can review the necessary changes there in another pull request.
