Chris Lattner b4a8fe8dcc Make the implicit-int handling error recovery stuff handle C++
nested name specifiers.  Now we emit stuff like:

t.cpp:8:13: error: unknown type name 'X'
static foo::X  P;
       ~~~~ ^

instead of:

t.cpp:8:16: error: invalid token after top level declarator
static foo::X  P;
               ^

This is inspired by a really awful error message I got from 
g++ when I misspelt diag::kind as diag::Kind.

Douglas Gregor fe3d7d0880 Make parsing a semantic analysis a little more robust following Sema
failures that involve malformed types, e.g., "typename X::foo" where
"foo" isn't a type, or "std::vector<void>" that doens't instantiate
properly.

Similarly, be a bit smarter in our handling of ambiguities that occur
in Sema::getTypeName, to eliminate duplicate error messages about
ambiguous name lookup.

This eliminates two XFAILs in test/SemaCXX, one of which was crying
out to us, trying to tell us that we were producing repeated error
messages.

Douglas Gregor b67535d1b6 Parsing and AST representation for dependent template names that occur
within nested-name-specifiers, e.g., for the "apply" in

  typename MetaFun::template apply<T1, T2>::type

At present, we can't instantiate these nested-name-specifiers, so our
testing is sketchy.

Daniel Dunbar a45cf5b6b0 Rename clang to clang-cc.
Tests and drivers updated, still need to shuffle dirs.

Douglas Gregor 04e9a03e6f Fix various problems with matching out-of-line definitions of static
class members to the corresponding in-class declaration.

Diagnose the erroneous use of 'static' on out-of-line definitions of
class members.

Douglas Gregor 7f74112756 Implement parsing of nested-name-specifiers that involve template-ids, e.g.,
std::vector<int>::allocator_type

When we parse a template-id that names a type, it will become either a
template-id annotation (which is a parsed representation of a
template-id that has not yet been through semantic analysis) or a
typename annotation (where semantic analysis has resolved the
template-id to an actual type), depending on the context. We only
produce a type in contexts where we know that we only need type
information, e.g., in a type specifier. Otherwise, we create a
template-id annotation that can later be "upgraded" by transforming it
into a typename annotation when the parser needs a type. This occurs,
for example, when we've parsed "std::vector<int>" above and then see
the '::' after it. However, it means that when writing something like
this:

  template<> class Outer::Inner<int> { ... };

We have two tokens to represent Outer::Inner<int>: one token for the
nested name specifier Outer::, and one template-id annotation token
for Inner<int>, which will be passed to semantic analysis to define
the class template specialization.

Most of the churn in the template tests in this patch come from an
improvement in our error recovery from ill-formed template-ids.
