Jakob Stoklund Olesen ac51533b8a Simplify RegScavenger::forward a bit more. 
Verify that early clobber registers and their aliases are not used.

All changes to RegsAvailable are now done as a transaction so the order of
operands makes no difference.

The included test case is from PR4686. It has behaviour that was dependent on the order of operands.
