target/mips: Simplify decode_opc_mxu() ifdef'ry
By making the prototype public and checking 'TARGET_LONG_BITS == 32' we let the compiler elide the decode_opc_mxu() call. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20210226093111.3865906-12-f4bug@amsat.org>
