from the ASTContext.
 - Doing so requires the compiler to generate null checks against the returned
   result, but the BumpPtrAllocator never returns null pointers.
 - The optimizer can usually eliminate such checks, but not always, so this
   gives us tighter codegen in some places.
 - It would be really nice if we could just use __builtin_unreachable or
   something to tell the optimizer that the allocator never returns null, but
   LLVM isn't currently that smart.

Patch from Sean Silva <silvas@purdue.edu>!

In the included testcase, soma thinks that we already have a definition after we
see the out of line decl. Codegen puts it in a deferred list, to be output if
a use is seen. This would break when we saw an explicit template instantiation
definition, since codegen would not be notified.

This patch adds a method to the consumer interface so that soma can notify
codegen that this decl is now required.

Fix a bug in the mangler where in 'namespace std { extern "C" {X;} }', X would not be seen to be in ::std::.

Migrate two other places where the same logic is used to use the helper function that already exists.

-Make sure we don't change to '__weak' a __block variable used as output.
-Make sure we don't apply __weak twice.

Avoid an unnecessary recursive loop between type canonicalization and NNS canonicalization which would (rarely) lead to memory corruption.  While I'm here, simplify.  Fixes PR12166.  Not committing a testcase because it's impossible to reduce it.

 - This is a more reliable default, as it behaves better on failure and also
   ensures that we create *new* files (instead of reusing existing inodes). This
   is useful for other applications (like lldb) which want to cache inode's to
   know when a file has been rewritten.

This is a preparation to adding an AST-based call graph to Analysis. The
existing call graph works with indexer entries. We might be able to
refactor it to use the AST based graph in the future.

(Minimal testing here as the only example that uses the API has been
completely broken, does not compile.)
