Log:
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.
