9e86f4364b Remove interprocedural-basic-aa and associated code. The AliasAnalysis 
interface needs implementations to be consistent, so any code which
wants to support different semantics must use a different interface.
It's not currently worthwhile to add a new interface for this new
concept.

Document that AliasAnalysis doesn't support cross-function queries.

8d121694a3 Generalize AAEval so that it can be used both per-function and 
interprocedurally. Note that as of this writing, existing alias
analysis passes are not prepared to be used interprocedurally.

fd447eff22 The FoldingSet hash data includes pointer values, so it isn't

4d52c6d622 Optimize ScalarEvolution's SCEVComplexityCompare predicate: don't go 
scrounging through SCEVUnknown contents and SCEVNAryExpr operands;
instead just do a simple deterministic comparison of the precomputed
hash data.

Also, since this is more precise, it eliminates the need for the slow
N^2 duplicate detection code.
