Moritz Roth 8c4e64af8a [Thumb] Make load/store optimizer less conservative. ...

If it's safe to clobber the condition flags, we can do a few extra things:
it's then possible to reset the base register writeback using a SUBS, so
we can try to merge even if the base register isn't dead after the merged
instruction.

This is effectively a (heavily bug-fixed) rewrite of r208992.
