022e782e75 [AArch64] Add support for __builtin_ms_va_list on aarch64 
Move builtins from the x86 specific scope into the global
scope. Their use is still limited to x86_64 and aarch64 though.

This allows wine on aarch64 to properly handle variadic functions.

c7d5c94f78 Support __builtin_ms_va_list. 
Summary:
This change adds support for `__builtin_ms_va_list`, a GCC extension for
variadic `ms_abi` functions. The existing `__builtin_va_list` support is
inadequate for this because `va_list` is defined differently in the Win64
ABI vs. the System V/AMD64 ABI.

Depends on D1622.
