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.

when processing a constraint we don't understand.  This allows the frontend
to gracefully fail.

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

When building PathDiagnostics for bug reports, generate a trimmed ExplodedGraph with a single path that BugReport objects can safely walk and introspect.

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.

when it is constructed via deserialization.  This is done by recording a flag
indicating that this is the case, and it deletes these objects by getting
the references stored in the ASTContext object.  This fixes some memory
leaks that occurs when we deserialize translation units from bitcode files.

The rationale between having TranslationUnit sometimes own these objects and
sometimes not is that a TranslationUnit object can be constructed from
state generated by the parser (Preprocessor; semantic analyzer, etc.), and thus
in these cases won't own the IdentifierTable or Selectors, etc.  During
deserialization, there is no Preprocessor, so somebody needs to own these
objects in order for them to be properly reclaimed.

Added "nonlval::LValAsInteger" to represent abstract LVals casted to integers, allowing us to track lvals when they are casted back to pointers.

HTMLDiagnostics now batches PathDiagnostics before emitting HTML in its dtor.
This is a workaround for a problem when we trampled the Preprocessor state
when highlighting macros (sometimes resulting in an assertion failure).

Added iterators, methods to find property and categories.

declarations. Fixed typos.

1. If we hit a semantic error, try harder to recover to emit
   diagnostics for later initializer errors (PR2241).
2. Don't leak parsed initializers on an error.

literal, indicate what character the error is about or where
it would be.  For example:

float f[] = { 1e  , 1ee0 };
