Sean Callanan 1249511024 Extended the UnknownAnyTy resolver to handle
blocks with unknown return types.  This allows
LLDB to call blocks even when their return types
aren't provided in the debug information.

Chad Rosier 64d6be979f [driver] What was implemented in r152130 was actually -fno-inline-functions, not
-fno-inline.

Ted Kremenek f7639e1b4a Add new code migrator support for migrating existing Objective-C code to use
the new Objective-C NSArray/NSDictionary/NSNumber literal syntax.

This introduces a new library, libEdit, which provides a new way to support
migration of code that improves on the original ARC migrator.  We now believe
that most of its functionality can be refactored into the existing libraries,
and thus this new library may shortly disappear.

Ted Kremenek e65b086e07 Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,
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.

Daniel Dunbar 492488271f AST: Move several Type::is...Type() functions to be inline.
- 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.

Richard Smith d67aea28f6 User-defined literals: reject string and character UDLs in all places where the
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.

Richard Smith f506eaf36d static_assert: Allow any string-literal as the message, not just a character

Rafael Espindola 189fa748ec Fix a small difference in sema and codegen views of what needs to be output.
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.

Daniel Dunbar ae77b3dfad Frontend: Default to creating output files using temporary files + rename.
- This is a more reliable default, as it behaves better on failure and also
   ensures that we create *new* files (instead of reusing existing inodes). This
   is useful for other applications (like lldb) which want to cache inode's to
   know when a file has been rewritten.
