Ted Kremenek f7141597e8 CF reference count checker: handle variadic functions that allocate CF objects. 
This fixes <rdar://problem/5886141>.

Part of this change resulted in creating sparser summaries.  I also added
some more comments and did some minor code cleanups.

Ted Kremenek b44485b835 Have ValidateOutputConstraint return false instead of firing an assertion 
when processing a constraint we don't understand.  This allows the frontend
to gracefully fail.

Evan Cheng 3980a7911a - Check if a register is livein before removing it. It may have already been removed. 
- Do not iterate over SmallPtrSet, the order of iteration is not deterministic.

sccp tracks getresult values, not call values in this
case.

Fix said code to handle merging return instructions together correctly
when handling multiple return values.

Ted Kremenek 21bf6006b0 For case statements involving enums, BugReporter now generates PathDiagnostics 
that say that we are jumping to "case a" instead of "case 0".

This is a feature implementation for <rdar://problem/5880430>.

Ted Kremenek dd43aeee54 Fixed: <rdar://problem/5881148> 
Problem:

In the recently refactored VisitDeref (which processes dereferences), we
were incorrectly skipping the node just generated for the subexpression
of the dereference.  This was a horrible regression.
