cmd/internal/obj: arm64 assembler support unshifted hi for large offsets
Extend splitImm24uScaled to support an unshifted hi value (hi <= 0xfff)
in addition to the shifted hi value (hi & ^0xfff000 == 0). This allows
load/store instructions to handle more offsets using ADD + load/store
sequences instead of falling back to the literal pool.
This will be used by a subsequent change to add FMOVQ support in SSA form.
