Duncan Sands a254acd1d3 Remove alloca tracking from nocapture analysis. Not only ...

was it not very helpful, it was also wrong!  The problem

a nocapture callee which dereferences it and returns the
original pointer.  But because it was a nocapture call we
think we don't need to track its uses, but we do.
