Make BlockDataRegion::referenced_vars_iterator an actual class that enforces that all MemRegions iterated over are VarRegions.

overloaded-operator resolution is wildly untested, but the parallel code for
methods seems to satisfy some trivial tests.

Also change some overload-resolution APIs to take a type instead of an expression,
which lets us avoid creating a spurious CXXThisExpr when resolving implicit
member accesses.

Add batch version of 'StoreManager::InvalidateRegion()' for invalidating multiple regions as once.  After adopting this in the CFRefCount::EvalCall(), we see a reduction in analysis time of 1.5% when analyzing all of SQLite3.

Do not include the 'this' pointer adjustment in the covariant return type. Instead, store it in the (now oddly named) Thunks map.

Move VtableBuilder::OverrideMethod out of line in preparation of other changes to it. No functionality change.

results in them (which we were doing intentionally as a stopgap).  Fix
an DeclContext lookup-table ordering problem which was causing UsingDecls to
show up incorrectly when looking for ordinary results.  And oh hey
Clang-Code-Syntax passes now.

Add a heuristic to the dead stores checker to prune dead stores for variables annotated with '__block'.  This is overly conservative, but now the analyzer doesn't report dead stores for variables that can be updated by a block call.

catch very many of them and if we caught all of them, the errors would
be annoying.  I'm working on this next.  WIP.
