__builtin_offsetof in the static analyzer that __builtin_offsetof is
not guaranteed to return an integer constant. We will need to shore
this up later, but now at least we have correct support for when this
*is* an integer constant.

to statically type various methods in SValuator/GRState as required either a
defined value or a defined-but-possibly-unknown value. This leads to various
logic cleanups in GRExprEngine, and lets the compiler enforce via type checking
our assumptions about what symbolic values are possibly undefined and what are
not.
Along the way, clean up some of the static analyzer diagnostics regarding the uses of uninitialized values.

Here we implement this as a precondition within GRExprEngine, even though it is
related to how BasicStoreManager and RegionStoreManager model 'self'
differently. Putting this as a high-level precondition is more general, which is
why it isn't in RegionStore.cpp.

Also fix a checker context bug: the Dst set is not always empty initially.
Because in GRExprEngine::CheckerVisit(), *CurrSet is used repeatedly.
So we removed the Dst.empty() condition in ~CheckerContext() when deciding
whether to do autotransision.

in the BugReport.
When all internal bug checking logic are moved to checkers, BuiltinBug will
not reference GRExprEngine, and FlushReports() will be not necessary, since
all bugs are emitted into the equivalent classes immediately.
For now just add a ctor with no arguments.

motivated from Shark profiles that shows that 'markLive' was very
heavy when using --analyzer-store=region. On my benchmark file, this
reduces the analysis time for --analyzer-store=region from 19.5s to
13.5s and for --analyzer-store=basic from 5.3s to 3.5s. For the
benchmark file, this is a reduction of about 30% analysis time for
both analysis modes (a huge win).

space within the MemberExpr for the nested-name-specifier and its
source range. We'll do the same thing with explicitly-specified
template arguments, assuming I don't flip-flop again.

pointers. Most logic cares first about whether or not a region is
symbolic, and second if represents code. This should fix a series of
silent corner case bugs (as well as simplify a bunch of code).

retain the qualifier (and its source range information) in a new
subclass of MemberExpr called CXXQualifiedMemberExpr. Provide
construction, transformation, profiling, printing, etc., for this new
expression type.
When a virtual function is called via a qualified name, don't emit a
virtual call. Instead, call that function directly. Mike, could you
add a CodeGen test for this, too?

implicit cast logic in RegionStoreManager to BasicStoreManager. This involved
moving CastRetriedVal from RegionStoreManager to StoreManager.

Now AnalysisManager is the only place we can get CodeDecl.
This leads to an API change: GRState::bindExpr() now takes the CFG argument.
