cmd/internal/obj/ppc64, cmd/link/internal/ppc64: Change function alignment to 16
The Power processor manual states that "Branches not from the last instruction
of an aligned quadword and not to the first instruction of an aligned quadword
cause inefficiencies in the IBuffer". This changes the function alignment from 8
to 16 bytes to comply with that.
Fixes #18963
