Add some boilerplate to report memory leaks at the end of an analyzed function.

Still need some boilerplate in BugReporter to report bugs at the end
of a function (not associated with a particular statement).

Changed behavior of how we handle "NULL" summaries: just call
...
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.

Teach InstCombine's ComputeMaskedBits to handle pointer expressions
...
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.

refactor Parser::ParseStructDeclaration to return a vector of uninterpreted
...
declarators. This allows the clients (C structs, objc classes, objc
properties, [future] C++ classes) etc, to do custom processing before invoking
an action.
This has two benefits in the short term:
1) objc ivar processing should be split out of ActOnField into its own ActOn method.
2) the new objc ivar action can take visibility info directly, eliminating
AllVisibilities in ParseObjCClassInstanceVariables.
3) objc properties can pass their own special sauce down to sema as well.
