[AArch64] Commonise some SVE FP patterns
This patch uses a single expander for generic FP binary optabs
that map to predicated SVE instructions. This makes them consistent
with the associated conditional optabs, which already work this way.
The patch also generalises the division handling to be one example
of a register-only predicated FP operation. The ACLE patches will
add FMULX to the same category.
