This fixes PR15289. This bug was introduced (recently) in r175215; collecting all std::vector references for candidate pairs to delete at once is invalid because subsequent lookups in the owning DenseMap could invalidate the references. bugpoint was able to reduce a useful test case. Unfortunately, because whether or not this asserts depends on memory layout, this test case will sometimes appear to produce valid output. Nevertheless, running under valgrind will reveal the error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175397 91177308-0d34-0410-b5e6-96231b3b80d8

; This is a bugpoint-reduced test case. It did not always assert, but does reproduce the bug

; and running under valgrind (or some similar tool) will catch the error.
