Remove 2 dead instruction from AArch64 back-end poly_tomont()

[rod-chapman]

Fixes #1656

1. Remove 2 dead instructions and re-assign registers
2. Re-apply SLOTHY
3. Re-autogen all files
4. Update HOL-Light bytecode for poly_tomont()

The HOL-Light proof scripts itself did not require modifiction

[rod-chapman]

On a Graviton4 (r8g) instance, the tests bench --components benchmark says exec time for poly_tomont() reduces from 58 to 56 cycles.
