Douglas Gregor 0286b46702 Only parse C++0x attribute specifiers in declarators when in C++0x
mode. This allows us to detect invalid VLAs in Objective-C++
mode. This should be the last of <rdar://problem/7660386>.

Douglas Gregor 337caf9e3e Implement C++ name lookup for instance variables of Objective-C classes
from an instance method. Previously, we were following the Objective-C
name lookup rules for ivars, which are of course completely different
from and incompatible with the Objective-C++ rules.

For the record, the Objective-C++ rules are the sane ones.

This is another part of <rdar://problem/7660386>.

Douglas Gregor cfd70242ca Make Sema::ActOnClassMessage robust when name lookup for the receiver
name finds something other than a TypedefDecl or an
ObjCInterfaceDecl. This is a small part of <rdar://problem/7660386>.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Daniel Dunbar df1cff7356 Remove excessive use of Carbon.h / Cocoa.h in clang tests.
- These kinds of "shotgun" tests are very slow, and do not belong in the
   regression suite. If these kinds of tests are regarded to have value, they
   should be added to the LLVM test-suite.

 - I would actually like to remove all of these tests, but I left Sema/carbon.c
   and SemaObjC/cocoa.m...

Steve Naroff 7cae42b07a This patch includes a conceptually simple, but very intrusive/pervasive change.
The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches.

This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic.

By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time. 

Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks.

Daniel Dunbar 4dbaaa6f43 Improve handling of (X86) target features.
- This is a WIP...

 - This adds -march= handling to the driver, and fixes the defaulting
   of -mcpu on Darwin (which was using the wrong test).

Instead of handling -m{sse, ...} in the driver, pass them to clang-cc as
 -target-feature [+-]name

In clang-cc, communicate with the (clang) target to discover the legal
features of a target, and the features which are enabled based on
-mcpu. This is currently hardcoded just enough to not be a feature
regression, we need to get this information from the backend's
TableGen information somehow.

This is used to construct the full list of features which are being
used, which is in turn used to initialize the predefines.

Daniel Dunbar 386ef885bb Pull clang-cc code for generating PTH files based on the input type.
- <rdar://problem/6741594> [pth] don't abuse -x to drive pth
   generation

 - Simpler, and fixes PR3915.

Cleanup test cases for PTH:
 - Update to use -emit-pth

 - Removed PTH test of carbon.c and cocoa.mm; these didn't actually
   verify anything, and since PTH is token based the extra coverage
   (over cocoa.m) isn't particularly helpful.

 - Split PTH tests in cocoa.m to cocoa-pth.m, solely to increase
   available parallelism when running tests.

Ted, could you update the PTH test cases (include-pth.c and
cocoa-pth.m) to have some sort of positive check that the PTH is
getting used? "# of PTH cache hits" or "tokens read from PTH cache"
statistics would work great. :)

Douglas Gregor e254f90d94 Initial implementation of argument dependent lookup (a.k.a. ADL,
a.k.a. Koenig lookup) in C++. Most of the pieces are in place, but for
two:

  - In an unqualified call g(x), even if the name does not refer to
    anything in the current scope, we can still find functions named
    "g" based on ADL. We don't yet have this ability.
  - ADL will need updating for friend functions and templates.

Douglas Gregor a29dc05eaf Add implicit conversions for Objective-C qualified ids, e.g.,
id<P0>

The intended overloading behavior of these entities isn't entirely
clear, and GCC seems to have some strange limitations (e.g., the
inability to overload on id<P0> vs. id<P1>). We'll want to revisit
these semantics and determine just how Objective-C++ overloading
should really work.

Fixed a few cases where we assumed the C++ definition of isObjectType,
