Re. comment #9

GCSE store motion is very broken, and it's really been like that for a long
time.  And it doesn't really do much, either, when you turn it on.  Sadly we
have nothing to replace it right now except the loop store motion in
tree-ssa-loop-im.c, which doesn't work as well as GCSE store motion due to
alias representation issues at the tree level.

We're just going to have to fix this one IMHO.
