Jakob Stoklund Olesen 0e4f7f92a2 Correctly handle <undef> tied uses when rewriting after a split. ...

This fixes PR10463. A two-address instruction with an <undef> use
operand was incorrectly rewritten so the def and use no longer used the
same register, violating the tie constraint.

Fix this by always rewriting <undef> operands with the register a def
operand would use.
