[X86] Enable constexpr on POPCNT intrinsics (PR31446)
This is a first step patch to enable constexpr support and testing to a large number of x86 intrinsics.
All I've done here is provide a DEFAULT_FN_ATTRS_CONSTEXPR variant to our existing DEFAULT_FN_ATTRS tag approach that adds constexpr on c++ builds. The clang cuda headers do something similar.
I've started with POPCNT mainly as its tiny and are wrappers to generic __builtin_* intrinsics which already act as constexpr.
