Roman Lebedev 78bd4231bf [InstCombine] PHI-aware aggregate reconstruction: properly handle duplicate predecessors 
While it may seem like we can just "deduplicate" the case where
some basic block happens to be a predecessor more than once,
which happens for e.g. switches, that is not correct thing to do.
We must actually add a PHI operand for each predecessor.

This was initially reported to me by David Major
as a clang crash during gecko build for android.
