[PATCH] AArch64: Remove redundant check in aarch64_simd_mov

[Wilco Dijkstra]

The split condition in aarch64_simd_mov uses aarch64_simd_special_constant_p.  
While
doing the split, it checks the mode before calling 
aarch64_maybe_generate_simd_constant.
This risky since it may result in unexpectedly calling aarch64_split_simd_move 
instead
of aarch64_maybe_generate_simd_constant.  Since the mode is already checked, 
remove the
spurious explicit mode check.

Passes bootstrap & regress, OK for commit?
