In fact, field-sensitive points-to analysis is probably not improving things
anyway - a testcase where it does is certainly welcome! - simply due to the
fact that the points-to analysis would need to be more clever than
load (partial-)redundancy elimination.  Where it could help is for IPA mode
though.  And likely it will rot very quickly if we disable it, but ...
it would be my prefered choice here.
