Also seems suspect, but harmless.

(1) Unnecessary () around ==.
(2) The call to decode_opc_mxu should be eliminated by the compiler because of
the constant false test. You can (a) retain the function above and omit the
new test, (b) add the new test and leave the function undefined, a diagnostic
link error, or you can re-declare the function with QEMU_ERROR.

This one won't be eliminated, and is an abort for MIPS64 per patch 8, so all
mips64 now aborts on startup.
