3e4b85cd99 only dereference iterator once in the loop 
(by caching the result we save a potentially expensive dereference)

also use typedefs to shorten type declarations

5338c9f877 Use std::vector rather than SmallVector here because SmallVector 
causes some versions of gcc to crash when building LLVM.

dcc1398f44 Do not use std::stack because it causes obscure failures when 
compiled with MSVC 2010 (PR7367).  Instead use a SmallVector.

2a08e2ce81 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.

properly handles instructions and arguments defined in different
functions, or across recursive function iterations.

d454f5c234 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.

is more consistent with the ConstantInt API.

490f4d7020 The FoldingSet hash data includes pointer values, so it isn't 
determinstic. Instead, give SCEV objects an arbitrary sequence
number.

65954b2eb4 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.

1865db1b89 LSR needs to remember inserted instructions even in postinc mode, because 
there could be multiple subexpressions within a single expansion which
require insert point adjustment. This fixes PR7306.

b5bf752087 Clear CachedFunctionInfo upon Pass::releaseMemory. Because ValueMap will abort 
on RAUW of functions, this is a correctness issue instead of a mere memory
usage problem.
