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.

Now bad callee is checked as a PreVisit to the CallExpr.

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).

symbolic, and second if represents code.  This should fix a series of
silent corner case bugs (as well as simplify a bunch of code).

Simplify 'Environment' to contain only one map from 'const Stmt*' to SVals, greatly simplifying the logic of the analyzer in many places.  We now only distinguish between block-level expressions and subexpressions in Environment::RemoveDeadBindings and GRState pretty-printing.

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?

Fix regression in BasicStoreManager caused by implicitly casting loaded values and trying to load/store from arrays.  RegionStoreManager already properly handles these cases well; we just need to gracefully not handle this case in BasicStoreManager.  This fixes PR 4781.
