its companion ObjCImplementationDecl.

Refactor some of RegionStore's InvalidateRegionsWorker class
into a 'ClusterAnalysis' parent class.  The idea is
to potentially reuse this for reworking RemoveDeadBindings.

Don't accidentally mark some functions in construction vtables as unused. Also land the test for a previous checkin, now that it's correct.

Statement expressions can be used in global- or namespace-scoped blocks

Create a new InjectedClassNameType to represent bare-word references to the
injected class name of a class template or class template partial specialization.
This is a non-canonical type;  the canonical type is still a template
specialization type.  This becomes the TypeForDecl of the pattern declaration,
which cleans up some amount of code (and complicates some other parts, but
whatever).

Fixes PR6326 and probably a few others, primarily by re-establishing a few
invariants about TypeLoc sizes.

When building construction vtables, we need to check if a primary virtual base is actually a primary virtual base in the layout class.

Improve vcall offset handling in construction vtables. With this we layout the construction vtables from the ABI examples correctly.

Delay codegen of vtables when handling implicit instantiations.

This fixes PR6474.

Fix file reference for derived and composite types. Now, dwarf writer uses strict verifier that ignores debug info for such types if their file info is unknown.

Value-initialize the written-builtin-specifiers field of DeclSpec, which
wasn't being initialized properly along the implicit-definition path.
