Standardize the parsing of function type attributes in a way that
follows (as conservatively as possible) gcc's current behavior: attributes
written on return types that don't apply there are applied to the function
instead, etc. Only parse CC attributes as type attributes, not as decl attributes;
don't accepet noreturn as a decl attribute on ValueDecls, either (it still
needs to apply to other decls, like blocks). Consistently consume CC/noreturn
information throughout codegen; enforce this by removing their default values
in CodeGenTypes::getFunctionInfo().

Fix two issues with the substitution of template template parameters
when instantiating the declaration of a member template:
- Only check if the have a template template argument at a specific position
when we already know that we have template arguments at that level;
otherwise, we're substituting for a level-reduced template template
parameter.
- When trying to find an instantiated declaration for a template
template parameter, look into the instantiated scope. This was a
typo, where we had two checks for TemplateTypeParmDecl, one of
which should have been a TemplateTemplateParmDecl.
With these changes, tramp3d-v4 passes -fsyntax-only.

Fix an obscure crash found in the Boost.MPL test suite, along with a
ton of potential crashes of the same kind. The fundamental problem is
that type creation was following a dangerous pattern when using its
FoldingSets:
1) Use FindNodeOrInsertPos to see if the type is available
2) If not, and we aren't looking at a canonical type, build the
canonical type
3) Build and insert the new node into the FoldingSet
The problem here is that building the canonical type can, in very rare
circumstances, force the hash table inside the FoldingSet to
reallocate. That invalidates the insertion position we computed in
step 1, and in step 3 we end up inserting the new node into the wrong
place. BOOM!
I've audited all of ASTContext, fixing this problem everywhere I found
it. The vast majority of wrong code was C++-specific (and *ahem*
written by me), so I also audited other major folding sets in the C++
code (e.g., template specializations), but found no other instances of
this problem.
which means that we pass 99.96% of all tests :) The resulting 27 tests are all LLVMC tests and seem to be because of differences in the clang and gcc drivers.
