Um, I don't think either of these should be changed. Since
we're talking about an auto-inc, this isn't an issue with the
use, it's more likely an issue with not registering the kill
somewhere.
In general gcse doesn't expect to have to deal with auto-inc,
since that's supposed to be generated later. Clearly someone
forgot about stack pushes. My guess is that the proper solution
is to add code to compute_sets to notice these.
Can you attach your preprocessed test case to the PR?
