Simplify the logic of getting hold of a PHI predecessor block. There is now a direct way from value-use-iterator to incoming block in PHINode's API. This way we avoid the iterator->index->iterator trip, and especially the costly getOperandNo() invocation. Additionally there is now an assertion that the iterator really refers to one of the PHI's Uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62869 91177308-0d34-0410-b5e6-96231b3b80d8
