We might end up with a trivial copy as the addend, and if so, we should ignore the corresponding FMA instruction. The trivial copy can be coalesced away later, so there's nothing to do here. We should not, however, assert. Fixes PR24544. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@245907 91177308-0d34-0410-b5e6-96231b3b80d8
