zatrazz requested review of this revision.
On AArch64 it allows use the native FP16 ABI (although libcalls are
not emitted for fptrunc/fpext lowering), while on other architectures
the expected current semantic is preserved (arm for instance).
For testing the _Float16 usage is enabled by architecture base,
currently only for arm, aarch64, and arm64.
