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.
