David Green 98c302baef [ARM] Ensure we update the correct flags in the peephole optimiser
The Arm peephole optimiser code keeps track of both an MI and a SubAdd that can
be used to optimise away a CMP. In the rare case that both are found and not
ruled-out as valid, we could end up setting the flags on the wrong one.

Instead make sure we are using SubAdd if it exists, as it will be closer to the
CMP.

The testcase here is a little theoretical, with a dead def of cpsr. It should
hopefully show the point.
