> In r235215, I added support for legalizing f16 type in the IR by promoting
> operations on f16 to f32 and using f16 <-> f32 conversions on load/store.
> With some backend patches, this promotion works successfully on ARM,
> AArch64, X86, X86-64, Mips and Mips64.
> Is it reasonable to expose the NativeHalfType LangOption in the command
> line?  Clang already exposes HalfArgsAndReturns langopt as
> '-fallow_half_arguments_and_returns '.
> Please advice.
