Andrew Trick acdb4aaf9b LSR: Don't optimize loops if an outer loop has no preheader. ...

LoopSimplify may not run on some outer loops, e.g. because of indirect
branches. SCEVExpander simply cannot handle outer loops with no preheaders.
Fixes rdar://10655343 SCEVExpander segfault.

LoopSimplify

Make loop preheader insertion in LoopSimplify handle the case where the loop header is a landing pad correctly (by splitting the landingpad out of the loop header). Make some adjustments to the rest of LoopSimplify to make it clear that the rest of LoopSimplify isn't making bad assumptions about the presence of landing pads. PR11575.
