## Message

```
stage1: use u16 for __truncxfhf2/__extendhfxf2 on non-Arm CPUs

Non-Arm CPUs use u16 as the parameter to __extendhfxf2 and the return value of
__truncxfhf2, so insert appropriate bitcasts in gen_soft_f80_widen_or_shorten.
Otherwise, LLVM might crash because the functions are called in a different way
than its compiler-rt definition.

This fixes stage1 build on SPARCv9, and possibly other non-x86, non-Arm CPUs.

```
