Owen Anderson d62d37225a Use the new addEscapingValue callback to update GlobalsModRef when GVN adds PHIs of GEPs. For the moment,
have GlobalsModRef handle this conservatively by simply removing the value from its maps.

Dan Gohman 9130bad71f Extend the AliasAnalysis::pointsToConstantMemory interface to allow it
to optionally look for constant or local (alloca) memory.

Teach BasicAliasAnalysis::pointsToConstantMemory to look through Select
and Phi nodes, and to support looking for local memory.

Remove FunctionAttrs' PointsToLocalOrConstantMemory function, now that
AliasAnalysis knows all the tricks that it knew.

Dan Gohman da85ed8541 Move NoAA out of BasicAliasAnalysis.cpp into its own file, now that
it doesn't have a special relationship with BasicAliasAnalysis
anymore.
