- Add -pic-level clang-cc option to specify the value for the define,
updated driver to pass this.
- Added __pic__
- Added OBJC_ZEROCOST_EXCEPTIONS define while I was here (to match gcc).

and are even set in C mode. As such, move them to Targets.cpp.
__OBJC_GC__ is also darwin specific, but seems reasonable to always
define it when in objc-gc mode.
This fixes rdar://6761450

Eventually, would be nice to be able to run these modifications even
when we don't want the warning or errors for the actual diagnostic.

From a front-end perspective, I believe this code should work for ObjC @-strings. At the moment, I believe we need to tweak the code generation for @-strings (which doesn't appear to handle them). Will be investigating.

- Temporarily undef'ed __OBJC2__ in nonfragile objc abi mode
as it was forcing ivar synthesis in a certain project which clang
does not yet support.

terminated with an EOF token. The condition it is trying to check for is
handled by this code above.
// Empty arguments are standard in C99 and supported as an extension in

- Make the Diagnostic::Level for PTH errors to be specified by the caller
clang (driver):
- Set the PTHManager diagnostic level to "Diagnostic::Error" for -include-pth
(a hard error) and Diagnostic::Warning for -token-cache (we can still
proceed).

Add a #include directive around the command line buffer so that
diagnostics generated from -include directives get diagnostics
like:
In file included from <built-in>:98:
In file included from <command line>:3:
./t.h:2:1: warning: type specifier missing, defaults to 'int'
b;
^

and the token after the # should be expanded if it is not a valid directive.
This allows us to transform things like:
#define FOO BAR
# FOO
into # BAR, even though FOO is not normally expanded for directives.
This should fix PR3833

diagnostics. This builds on the patch that Sebastian committed and
then revert. Major differences are:
- We don't remove or use the current ".def" files. Instead, for now,
we just make sure that we're building the ".inc" files.
- Fixed CMake makefiles to run TableGen and build the ".inc" files
when needed. Tested with both the Xcode and Makefile generators
provided by CMake, so it should be solid.
- Fixed normal makefiles to handle out-of-source builds that involve
the ".inc" files.
I'll send a separate patch to the list with Sebastian's changes that
eliminate the use of the .def files.

themselves are.
This speeds up -Eonly cocoa.h pth by ~4%, fsyntax-only is barely measurable.
