GRSimpleVals::EvalCal(), and don't change reference counts.

Remove "getDoNothingSummary()", as a NULL summary does the same thing.

Added temporary hack for the "Get" rule for objects that return a pointer type:
treat them as non-owned CF objects.

Added test case to detect the release of a non-owned object.

2) the new objc ivar action takes visibility info directly, eliminating

in addition to integer expressions. Rewrite GetOrEnforceKnownAlignment
as a ComputeMaskedBits problem, moving all of its special alignment
knowledge to ComputeMaskedBits as low-zero-bits knowledge.

Also, teach ComputeMaskedBits a few basic things about Mul and PHI
instructions.

This improves ComputeMaskedBits-based simplifications in a few cases,
but more noticeably it significantly improves instcombine's alignment
detection for loads, stores, and memory intrinsics.
