MIPS: mark intrinsics IntrNoMem so all patterns using them are consistent.

This is apparently a bit of a white lie (they can affect DSPControl for
overflow etc) but similar to how we currently handle floating-point operations.
When it becomes relevant the whole lot can be reviewed properly.

C compilations as well and these flags don't make any sense there.
