The function aarch64_output_simd_mov_imm_low in GCC’s AArch64 backend emits an instruction directly and returns an empty string. Since this empty string is a string literal, this commit changes the return type of the function to const char * from char *. This resolves a compilation error (-Werror=write-strings) that arises when the compiler prevents assigning a string literal to a non-const char *.
