This allows it to accurately measure tokens, so that we get:
t.cpp:8:13: error: unknown type name 'X'
static foo::X P;
~~~~~^
instead of the woefully inferior:
t.cpp:8:13: error: unknown type name 'X'
static foo::X P;
~~~~ ^
Most of this is just plumbing to push the reference around.

t.c:3:8: warning: extra tokens at end of #endif directive

^
//
Don't do this in strict-C89 mode because bcpl comments aren't
valid there, and it is too much trouble to analyze whether
C block comments are safe.

- Ted, please check.
- Missing test case because PTH won't reliably cache the tokens in a
test case. *cough*

buffer generated for the current translation unit. If they are
different, complain and then ignore the PCH file. This effectively
checks for all compilation options that somehow would affect
preprocessor state (-D, -U, -include, the dreaded -imacros, etc.).
When we do accept the PCH file, throw away the contents of the
predefines buffer rather than parsing them, since all of the results
of that parsing are already stored in the PCH file. This eliminates
the ugliness with the redefinition of __builtin_va_list, among other
things.

PCH. This works now, except for limitations not being able to do things
with identifiers. The basic example in the testcase works though.

Preprocessor.cpp
into clang-cc.cpp. This makes it so clang-cc constructs the *entire* predefines
buffer, not just half of it. A bonus of this is that we get to kill a copy
of DefineBuiltinMacro.

improvement, source locations read from the PCH file will properly
resolve to the source files that were used to build the PCH file
itself.
Once we have the preprocessor state stored in the PCH file, source
locations that refer to macro instantiations that occur in the PCH
file should have the appropriate instantiation information.

- Add -static-define option driver can use when __STATIC__ should be
defined (instead of __DYNAMIC__).
- Don't set __OPTIMIZE_SIZE__ on Os, __OPTIMIZE_SIZE__ is tied to Oz.
- Set __NO_INLINE__ following GCC 4.2.
- Set __GNU_GNU_INLINE__ or __GNU_STDC_INLINE__ following GCC 4.2.
- Set __EXCEPTIONS for Objective-C NonFragile ABI.
- Set __STRICT_ANSI__ for standard conforming modes.
- I added a clang style test case in utils for this, but its not
particularly portable and I don't think it belongs in the test
suite.

updated driver to pass this.

__OBJC_GC__ is also darwin specific, but seems reasonable to always
define it when in objc-gc mode.

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.

basic tests. Chris Goller has graciously offered to write some test to help validate UCN support.
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.

- 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

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.

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.
