Adhemerval Zanella c288715e95 [compiler-rt] [builtins] Use _Float16 on extendhfsf2, truncdfhf2 __truncsfhf2 if available
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.
