In the case where the constant comes from a cloned cast instruction, the materialization code has to go before the cloned cast instruction. This commit fixes the method that finds the materialization insertion point by making it aware of this case. This fixes <rdar://problem/15532441> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206913 91177308-0d34-0410-b5e6-96231b3b80d8
