clang-cl gives us the option of changing a function to use the SystemV ABI:
https://clang.llvm.org/docs/AttributeReference.html#sysv-abi
By using this on functions on the C++ / JIT boundaries, we can use the same codepaths for function calls and the same register mappings between Windows and Linux / Mac / BSD.
JS LLInt was completed in bug 274064 and Baseline JIT in bug 275213 so there's no blockers for this.
