Richard Henderson 6597c28d61 target/openrisc: Optimize for r0 being zero ... The HW does not special-case r0, but the ABI specifies that r0 should contain 0. If we expose this fact to the optimizer, we can simplify a lot of the generated code. We must of course verify that r0==0, but that is trivial to do with a TB flag.
