[AArch64] Promote f16 operations to f32.
For the most common ones (such as fadd), we already did the promotion.
Do the same thing for all the others.
Currently, we'll just crash/assert on all these operations, as
there's no hardware or libcall support whatsoever.
f16 (half) is specified as an interchange - not arithmetic - format,
and is expected to be promoted to single-precision for arithmetic
operations.
While there, teach the legalizer about promoting some of the (mostly
floating-point) operations that we never needed before.
