Move a method from IdentifierTable.h out of line and remove the SmallString include.
Fix all the transitive include users.

Make the loading of information attached to an IdentifierInfo from an
AST file more lazy, so that we don't eagerly load that information for
all known identifiers each time a new AST file is loaded. The eager
reloading made some sense in the context of precompiled headers, since
very few identifiers were defined before PCH load time. With modules,
however, a huge amount of code can get parsed before we see an
@import, so laziness becomes important here.
The approach taken to make this information lazy is fairly simple:
when we load a new AST file, we mark all of the existing identifiers
as being out-of-date. Whenever we want to access information that may
come from an AST (e.g., whether the identifier has a macro definition,
or what top-level declarations have that name), we check the
out-of-date bit and, if it's set, ask the AST reader to update the
IdentifierInfo from the AST files. The update is a merge, and we now
take care to merge declarations before/after imports with declarations
from multiple imports.
The results of this optimization are fairly dramatic. On a small
application that brings in 14 non-trivial modules, this takes modules
from being > 3x slower than a "perfect" PCH file down to 30% slower
for a full rebuild. A partial rebuild (where the PCH file or modules
can be re-used) is down to 7% slower. Making the PCH file just a
little imperfect (e.g., adding two smallish modules used by a bunch of
.m files that aren't in the PCH file) tips the scales in favor of the
modules approach, with 24% faster partial rebuilds.
This is just a first step; the lazy scheme could possibly be improved
by adding versioning, so we don't search into modules we already
searched. Moreover, we'll need similar lazy schemes for all of the
other lookup data structures, such as DeclContexts.

now that we have a centralized place to do so, add some using declarations for
some common llvm types: stringref and smallvector. This cleans up the codebase
quite a bit.

When we're inserting a synthesized label declaration for a
forward-looking "goto" statement, make sure to insert it *after* the
last declaration in the identifier resolver's declaration chain that
is either outside of the function/block/method's scope or that is
declared in that function/block/method's specific scope. Previously,
we could end up inserting the label ahead of declarations in inner
scopes, confusing C++ name lookup.
Fixes PR9491/<rdar://problem/9140426> and <rdar://problem/9135994>.
Note that the crash-on-invalid PR9495 is *not* fixed. That's a
separate issue.

When synthesizing a label declaration based on a goto statement that
cannot yet be resolved, be sure to push the new label declaration into
the right place within the identifier chain. Otherwise, name lookup in
C++ gets confused when searching for names that are lexically closer
than the label. Fixes PR9463.

Support explicit template specialization and instantiation for members
of a C++0x inline namespace within enclosing namespaces, as noted in
C++0x [namespace.def]p8.
Fixes <rdar://problem/9006349>, a libc++ failure where Clang was
rejected an explicit specialization of std::swap (since libc++ puts it
into an inline, versioned namespace std::__1).

Another step in the process of making the parser depend on Sema:
- move DeclSpec &c into the Sema library
- move ParseAST into the Parse library
Reflect this change in a thousand different includes.
Reflect this change in the link orders.
