aarch64_output_simd_mov_imm_low emits the instruction directly using
output_asm_insn and returns an empty string to indicate that no further
template needs to be emitted. Since the returned empty string is a string
literal, the function should return const char * rather than char *.
This fixes a bootstrap failure with -Werror=write-strings.
gcc/ChangeLog:
* config/aarch64/aarch64-protos.h (aarch64_output_simd_mov_imm_low):
Change return type to const char *.
* config/aarch64/aarch64.cc (aarch64_output_simd_mov_imm_low): Likewise.
