handling the parsing of scanf format strings and hooking the checking into Sema.
Most of this checking logic piggybacks on what was already there for checking printf format
strings, but the checking logic has been refactored to support both.

What is left to be done is to support argument type checking in format strings and of course
fix the usual tail of bugs that will follow.

like we do with printf functions.  Follow-up work is needed to add similar support
for fscanf et al.

This is to support format-string checking for scanf functions.

 - This issue here is that /usr/include/Blocks.h wants to define some of the
   block runtime globals as weak, depending on the target. This doesn't work in
   Clang because we aren't using the AST decl for these globals.

 - The fix is a pretty gross hack which just watches all the decls for the
   specific blocks globals we need to know about; if we see one we use it,
   otherwise we use the hand coded type.

   In time, I would like to clean this up by changing IRgen to ask Sema/AST for
   the decl, which would then be lazily loaded from the builtin table if
   necessary. This could be used in a whole host of places in IRgen and would
   get rid of a lot of grotty hand coding of LLVM IR; however, we need some
   extra Sema support for this as well as support for builtin global variables.

parser is looking at a declaration or an expression, use a '=' to
conclude that we are parsing a declaration.

This is wrong. However, our previous approach of finding a comma after
the '=' is also wrong, because the ',' could be part of a
template-argument-list. So, for now we're going to use the same wrong
heuristic as GCC and Visual C++, because less real-world code is
likely to be broken this way. I've opened PR7655 to keep track of our
wrongness; note also the XFAIL'd test.
