Emit SIMD moves as mov
SIMD moves are currently emitted as ORR. Change this to use the MOV
pseudo instruction just like integer moves (the ARM-ARM states MOV is the
preferred disassembly), improving readability of -S output.
gcc/
* config/aarch64/aarch64.md (movti_aarch64):
Emit mov rather than orr.
(movtf_aarch64): Likewise.
* config/aarch64/aarch64-simd.md (aarch64_simd_mov):
Emit mov rather than orr.
