Applied the fixups suggested in the previous review, cheers.
This patch allows the AArch64 back end to emit the half-precision variants of FCMP and FCMPE, given the target supports FEAT_FP16. Previously, such comparisons would be unnecessarily promoted to single-precision. The latest documentation of these instructions can be found here: https://developer.arm.com/documentation/ddi0602/2024-12 Successfully bootstrapped and regtested on aarch64-linux-gnu. OK for stage 1?
