    AArch64: Remove redundant check in aarch64_simd_mov
    
    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.
    
    gcc/ChangeLog:
    
            * config/aarch64/aarch64-simd.md (aarch64_simd_mov<VQMOV:mode>):
            Remove redundant mode check.
