Chandler Carruth 6527ecc918 Teach MBP to force-merge layout successors for blocks with unanalyzable ...

branches that also may involve fallthrough. In the case of blocks with
no fallthrough, we can still re-order the blocks profitably. For example
instruction decoding will in some cases continue past an indirect jump,
making laying out its most likely successor there profitable.

Note, no test case. I don't know how to write a test case that exercises
this logic, but it matches the described desired semantics in
discussions with Jakob and others. If anyone has a nice example of IR
that will trigger this, that would be lovely.

Also note, there are still assertion failures in real world code with
this. I'm digging into those next, now that I know this isn't the cause.

Don't try to loop on iterators that are potentially invalidated inside the loop. Fixes PR11361!
