the old builder API.  This percolated a bunch of changes up to the
Checker class (where CheckLocation has been renamed VisitLocation) and
GRExprEngine.  ProgramPoint now has the notion of a "LocationCheck"
point (with PreLoad and PreStore respectively), and a bunch of the old
ProgramPoints that are no longer used have been removed.

This is reasonable because people know what they are doing when they 
intentionally dereference the pointer.
So now we only emit warning when a pointer variable is use literally.

Use SaveAndRestore to simplify logic in LiveVariables::runOnAllBlocks().  Patch by Kovarththanan Rajaratnam!

llvm-svn: 86343

Remove Checker::CheckType() (and instead using CheckerVisitor::PreVisitDeclStmt()), and refactor VLASizeChecker to have only one Checker subclass (not two) and to not use the node builders directly (and instead use the newer CheckerContext).

llvm-svn: 86329

Make the VLASizeChecker implementation private, and its creation only known to GRExprEngineInternalChecks.cpp.

Minor cleanup: use BuiltinBug (which will soon be renamed) for DeferenceChecker and friends so that they always report the same bug type.
