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.

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.

When a function or variable somehow depends on a type or declaration
that is in an anonymous namespace, give that function or variable
internal linkage.
This change models an oddity of the C++ standard, where names declared
in an anonymous namespace have external linkage but, because anonymous
namespace are really "uniquely-named" namespaces, the names cannot be
referenced from other translation units. That means that they have
external linkage for semantic analysis, but the only sensible
implementation for code generation is to give them internal
linkage. We now model this notion via the UniqueExternalLinkage
linkage type. There are several changes here:
- Extended NamedDecl::getLinkage() to produce UniqueExternalLinkage
when the declaration is in an anonymous namespace.
- Added Type::getLinkage() to determine the linkage of a type, which
is defined as the minimum linkage of the types (when we're dealing
with a compound type that is not a struct/class/union).
- Extended NamedDecl::getLinkage() to consider the linkage of the
template arguments and template parameters of function template
specializations and class template specializations.
- Taught code generation to rely on NamedDecl::getLinkage() when
determining the linkage of variables and functions, also
considering the linkage of the types of those variables and
functions (C++ only). Map UniqueExternalLinkage to internal
linkage, taking out the explicit checks for
isInAnonymousNamespace().
This fixes much of PR5792, which, as discovered by Anders Carlsson, is
actually the reason behind the pass-manager assertion that causes the
majority of clang-on-clang regression test failures. With this fix,
Clang-built-Clang+LLVM passes 88% of its regression tests (up from
67%). The specific numbers are:
LLVM:
Expected Passes : 4006
Expected Failures : 32
Unsupported Tests : 40
Unexpected Failures: 736
Clang:
Expected Passes : 1903
Expected Failures : 14
Unexpected Failures: 75
Overall:
Expected Passes : 5909
Expected Failures : 46
Unsupported Tests : 40
Unexpected Failures: 811
Still to do:
- Improve testing
- Check whether we should allow the presence of types with
InternalLinkage (in addition to UniqueExternalLinkage) given
variables/functions internal linkage in C++, as mentioned in
PR5792.
- Determine how expensive the getLinkage() calls are in practice;
consider caching the result in NamedDecl.
- Assess the feasibility of Chris's idea in comment #1 of PR5792.

not build a subregion map and instead do a single scan of the store.
This is done by building "region clusters" that represent the
collection of regions that have the same base region. Invalidating
any region in a cluster means that they all should get invalidated.
This change brought out a point that Zhongxing mentioned to me
offline: the flattened memory binding has issues distinguishing
between direct and default bindings. For example, setting the default
value for an entire struct is the same as binding to the first
element. To address this problem, I moved the binding "tag" (Direct
or Default) from BindingVal to BdingKey (and removed BindingVal
entirely). This requires us to do double lookups in some cases; and
there is still much more cleanup that can be done.
