Florian Hahn ae8e83e5e7 [PredicateInfo] Use custom mangling to support ssa_copy with unnamed types.
This is a workaround and it would be better to fix this generally, but
doing it generally is quite tricky. See D48541 and PR38117.

Doing it in PredicateInfo directly allows us to use the type address to
differentiate different unnamed types, because neither the created
declarations nor the ssa_copy calls should be visible after
PredicateInfo got destroyed.

Daniel Berlin 4ddfe6915d PredicateInfo: Support switch statements
Summary:
Depends on D29606 and D29682

Makes us pass GVN's edge.ll (we also will pass a few other testcases
they just need cleaning up).

Thoughts on the Predicate* hiearchy of classes especially welcome :)
(it's not clear to me how best to organize it, and currently, the getBlock* seems ... uglier than maybe wasting a field somewhere or something).
