e88168ae6e Use Sema's MarkDeclarationReferenced, which takes care of templates, instead of calling Decl's setUsed directly.

743682bb9f Re-work the handling of implicit 'this' arguments and silly GCC-style attribute 
argument indexes. This handles the offsets in a consistent manner for all of
the attributes which I saw working with these concepts. I've also added tests
for the attribute that motivated this: nonnull.

I consolidated the tests for format attributes into one file, and fleshed them
out a bit to trigger more of the warning cases. Also improved the quality of
some of the diagnostics that occur with invalid argument indices.

The only really questionable change here is supporting the implicit this
argument for the ownership attribute. I'm not sure it's really a sensible
concept there, but implemented the logic for consistency.

118baf7611 Add support for "neon_vector_type" and "neon_polyvector_type" attributes 
to create the special Neon vector types.  These are intended to be used in
Clang's version of <arm_neon.h> to define special Neon vector types that will
be mangled according to ARM's ABI.

0f107e4386 Relax __attribute_((nonnull)) checking to allow the attribute on functions with no pointer arguments. GCC doesn't warn

6b48873d50 Pull DelayedDiagnostic and AccessedEntity out into their own header. 
This works courtesy of the new SmallVector<..., 0> specialization that
doesn't require a complete type.  Note that you'll need to pull at least
SmallVector.h from LLVM to compile successfully.

dcfba7b35b Generate Attr subclasses with TableGen. 
Now all classes derived from Attr are generated from TableGen.
Additionally, Attr* is no longer its own linked list; SmallVectors or
Attr* are used. The accompanying LLVM commit contains the updates to
TableGen necessary for this.

Some other notes about newly-generated attribute classes:

 - The constructor arguments are a SourceLocation and a Context&,
   followed by the attributes arguments in the order that they were
   defined in Attr.td

 - Every argument in Attr.td has an appropriate accessor named getFoo,
   and there are sometimes a few extra ones (such as to get the length
   of a variadic argument).

Additionally, specific_attr_iterator has been introduced, which will
iterate over an AttrVec, but only over attributes of a certain type. It
can be accessed through either Decl::specific_attr_begin/end or
the global functions of the same name.
