rGcaa755f90e37: [BasicAA] Make BasicAA a cfg pass.
rG0cecafd647cc: [BasicAA] Make BasicAA a cfg pass.
Summary

Part of the changes in D44564 made BasicAA not CFG only due to it using
PhiAnalysisValues which may have values invalidated.
Subsequent patches (rL340613) appear to have addressed this limitation.

BasicAA should not be invalidated by non-CFG-altering passes.
A concrete example is MemCpyOpt which preserves CFG, but we are testing
it invalidates BasicAA.
