NSNumber, and boolean literals.  This includes both Sema and Codegen support.
Included is also support for new Objective-C container subscripting.

My apologies for the large patch.  It was very difficult to break apart.
The patch introduces changes to the driver as well to cause clang to link
in additional runtime support when needed to support the new language features.

Docs are forthcoming to document the implementation and behavior of these features.

 - These functions are both (a) very commonly called and (b) excellent
   candidates for CSE in the callers in which they are commonly used.
 - That isHalfType() is hot makes me sad, but it is trivially when inlined (and
   a huge waste of time when not!!!).
 - The extra IsEnumDeclComplete() function is a hack to break the cycle between
   Type.h and Decl.h, I'm not sure of how to do this more cleanly, but am open
   to ideas.

grammar requires a string-literal and not a user-defined-string-literal. The
two constructs are still represented by the same TokenKind, in order to prevent
a combinatorial explosion of different kinds of token. A flag on Token tracks
whether a ud-suffix is present, in order to prevent clients from needing to look
at the token's spelling.

The latter is just a worse version of the former.

Teach SimpleSValBuilder that (in the absence of more information) stack memory doesn't alias symbolic memory.  This is a heuristic/hack, but works well in practice.  Fixes <rdar://problem/10978247>.

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.
