Yes I expected failures to happen in reassoc due it not being well tested
before and now my patch is forcing the path inside reassoc being a lot more
than before. Most likely you could get a test case that exposes this before my
patch.

This is a bug in my reassoc changes, update_ops uses is_reassociable_op and
has_single_use predicates and expects to match exactly what get_ops did, but if
some SSA_NAME has say two imm uses during get_ops, one of those could be gone
because of earlier update_ops or GIMPLE_COND changes processing and then
update_ops can recurse on something get_ops has not. Will think about it
tomorrow.
