support building for arm64ec

Browse source 
ARM64EC is a custom ABI designed to allow ARM64 code to directly call into x64 code and vice-versa. In order to facilitate this, __x86_64__ (in llvm) and _M_X64 (in msvc) are both defined, but most x64 intrinsics aren't supported, so don't attempt to use them.
