When checking whether we can place a base subobject at an offset, we don't need to go past the highest offset that's known to contain an empty base subobject.

typedef'ed function types until such time as we decide not.

Fixed Objective-C type encoding for bitfields for the GNU runtime to match the encoding used by GCC.

This is required in order to test:

The ASTImporter should set base classes after formally entering the definition.

bring in the entire lookup table at once.

Also, give ExternalSemaSource's vtable a home.  This is important because otherwise
any reference to it will cause RTTI to be emitted, and since clang is compiled
with -fno-rtti, that RTTI will contain unresolved references (to ExternalASTSource's
RTTI).  So this change makes it possible to subclass ExternalSemaSource from projects
compiled with RTTI, as long as the subclass's home is compiled with -fno-rtti.

The macros required for DeclNodes use have changed to match the use of
StmtNodes. The FooFirst enumerator constants have been named firstFoo
to match usage elsewhere.

Turn on the new empty base subobject tracking code. It's a bit faster than the previous code. However, it still has quadratic performance, something which I intend to fix shortly in a subsequent patch.

Rework the way virtual primary bases are added when laying out classes. Instead of doing it as a separate step, we now use the BaseSubobjectInfo and use it when laying out the bases. This fixes a bug where we would either not add a primary virtual base at all, or add it at the wrong offset.

Change RecordLayoutBuilder::LayoutNonVirtualBase to take a BaseSubobjectInfo. No functionality change.

Move computing the base subobject info for a class into the RecordLayoutBuilder because we're going to need it to be able to correctly add offsets for primary virtual bases.

the x86-64 __va_list_tag with this attribute.  The attribute causes the
affected type to behave like a fundamental type when considered by ADL.

(x86-64 is the only target we currently provide with a struct-based
__builtin_va_list)

 - Docs are fairly sketchy, if someone wants to pore through gcc to look for
   holes I'd appreciate any failing test cases!
