[BOLT] Fix shrink wrapping to check pops
Summary:
Shrink wrapping has a mode where it will directly move push
pop pairs, instead of replacing them with stores/loads. This is an
ambitious mode that is triggered sometimes, but whenever matching with
a push, it would operate with the assumption that the restoring
instruction was a pop, not a load, otherwise it would assert. Fix this
assertion to bail nicely back to non-pushpop mode (use regular store and
load instructions).
