hipe_x86: LeaToAdd peephole rule
Although LEA is useful for three-address form adds, sometimes it is used
where a normal add would have sufficed (due to the addition being the
last use of one of the operands; but RTL lowering does not know that as
it does not have liveness information). As a workaround, we convert LEA
back to ADD when the destination is the same as one of the operands.
