Jit_Integer: Handle NOP case where RA == RS for ori

ori can be used as a NOP if the two register operands are the same, and
the immediate is zero, not only if the two register operands are r0.

Also removes the check for !inst.Rc, as ori only has one encoding, and
said encoding doesn't even have a record bit in it.
