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.

 - This is much faster, as it avoids the overhead of dumping an AST file to disk and reloading it.
 - For debugging purposes, there is a clang_setUseExternalASTGeneration hook which can be used to disable this.

On the Sketch Cocoa app, the speedup is pretty nice, especially when using a PCH file while scanning the source:

Wall time to c-index-test all files (no PCH):
Old: 23.4221
New: 12.3884

Wall time to c-index-test all files (with a PCH, and "local" mode):
Old: 10.9233
New:  1.9038
