AArch64: Improve codegen in AdvSIMD pow
Remove spurious ADRP. Improve memory access by shuffling constants and
using more indexed MLAs.
A few more optimisation with no impact on accuracy
- force fmas contraction
- switch from shift-aided rint to rint instruction
Between 1 and 5% throughput improvement on Neoverse
V1 depending on benchmark.
