I've added a new test case that causes the scalarizer to try and use dead-and-erased values - caused by the basic blocks not being in domination order within the function. To fix this, instead of iterating through the blocks in function order, I walk them in reverse post order. Differential Revision: https://reviews.llvm.org/D52540 llvm-svn: 344128
