The 32-bit MOVZ immediates are equivalent, MOVN never overlaps, and
MOVI has some overlaps . Since we allow all 3
Sorry for the very long delay in reviewing this.

Hi Richard,
Here is the immediate cleanup splitoff from the previous patch:
Simplify, refactor and improve various move immediate functions.
Allow 32-bit MOVZ/N as a valid 64-bit immediate which removes special
cases in aarch64_internal_mov_immediate. Add new constraint so the movdi
pattern
