Douglas Gregor 8b7d403684 Allow C++0x enumerations with a fixed underlying type in

Douglas Gregor bab8a96f2f Implement the Objective-C 'instancetype' type, which is an alias of
'id' that can be used (only!) via a contextual keyword as the result
type of an Objective-C message send. 'instancetype' then gives the
method a related result type, which we have already been inferring for
a variety of methods (new, alloc, init, self, retain). Addresses
<rdar://problem/9267640>.

Argyrios Kyrtzidis 5cec2aea3f Support code-completion for C++ inline methods and ObjC buffering methods.
Previously we would cut off the source file buffer at the code-completion
point; this impeded code-completion inside C++ inline methods and,
recently, with buffering ObjC methods.

Have the code-completion inserted into the source buffer so that it can
be buffered along with a method body. When we actually hit the code-completion
point the cut-off lexing or parsing.

Fariborz Jahanian bd0642fede objective-c - This patch buffers method implementations
and does the Sema on their body after the entire 
class/category @implementation is seen. This change allows messaging 
of forward private methods, as well as, access to 
synthesized ivars of properties with foward synthesize
declarations; among others. In effect, this patch removes
several restrictions placed on objective-c due to in-place
semantics processing of methods.

Douglas Gregor 081425343b Introduce support for a simple module import declaration, which
loads the named module. The syntax itself is intentionally hideous and
will be replaced at some later point with something more
palatable. For now, we're focusing on the semantics:
  - Module imports are handled first by the preprocessor (to get macro
  definitions) and then the same tokens are also handled by the parser
  (to get declarations). If both happen (as in normal compilation),
  the second one is redundant, because we currently have no way to
  hide macros or declarations when loading a module. Chris gets credit
  for this mad-but-workable scheme.
  - The Preprocessor now holds on to a reference to a module loader,
  which is responsible for loading named modules. CompilerInstance is
  the only important module loader: it now knows how to create and
  wire up an AST reader on demand to actually perform the module load.
  - We search for modules in the include path, using the module name
  with the suffix ".pcm" (precompiled module) for the file name. This
  is a temporary hack; we hope to improve the situation in the
  future.

Douglas Gregor 69f74f80db Introduce a -cc1 option "-emit-module", that creates a binary module
from the given source. -emit-module behaves similarly to -emit-pch,
except that Sema is somewhat more strict about the contents of
-emit-module. In the future, there are likely to be more interesting
differences.

Caitlin Sadowski 4b1e8399c2 Thread Safety: Added basic argument parsing for all new attributes.
This patch special cases the parser for thread safety attributes so that all
attribute arguments are put in the argument list (instead of a special
parameter) since arguments may not otherwise resolve correctly without two-token
lookahead.

This patch also adds checks to make sure that attribute arguments are
lockable objects.

Chandler Carruth a88a221855 Move the rest of the preprocessor terminology from 'instantiate' and
variants to 'expand'. This changed a couple of public APIs, including
one public type "MacroInstantiation" which is now "MacroExpansion". The
rest of the codebase was updated to reflect this, especially the
libclang code. Two of the C++ (and thus easily changed) libclang APIs
were updated as well because they pertained directly to the old
MacroInstantiation class.

No functionality changed.
