When we form a new function/class template specialization, we first
search for the specialization (in a folding set) and, if not found
form a *Decl that is then inserted into that folding set. In rare
cases, the folding set may be reallocated between the search and the
insertion, causing a crash. No test case, because triggering rehashing
consistently in a small test case is not feasible. Fixes
<rdar://problem/11115071>.

Unify and fix our checking of C++ [dcl.meaning]p1's requirements
concerning qualified declarator-ids. We now diagnose extraneous
qualification at namespace scope (which we had previously missed) and
diagnose these qualification errors for all kinds of declarations; it
was rather uneven before. Fixes <rdar://problem/11135644>.

[analyzer] Refactor: Use Decl when determining if the Block belongs to
the root function.

(This is a bit cleaner then using the StackFrame.)

[analyser] Stats checker: do not mark a node as exhausted if we will
retry without inlining.

When we can't prove that the target of an aggregate copy is
a complete object, the memcpy needs to use the data size of
the structure instead of its sizeof() value.  Fixes PR12204.
