Crash reproduction case
Since SVN r336812 (or r336804), building of quite a few different projects
start triggering asserts like this:
clang: ../lib/Transforms/Vectorize/SLPVectorizer.cpp:1391: void
llvm::slpvectorizer::BoUpSLP::buildTree_rec(llvm::ArrayRef<llvm::Value*>,
unsigned int, int): Assertion `(allConstant(VL) || allSameType(VL)) && "Invalid
types!"' failed.
