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.

functions that don't already have a (dynamic) alloca.
Dynamic allocas cause inefficient codegen and we shouldn't

the tests.
