3ad53483fb Add LangOptions::NeXTRuntime. 
- Wired to -fnext-runtime and -fgnu-runtime options.
 - Defaults to GNU, no autoselection for NeXT.

Emit NeXT OBJC_IMAGE_INFO marker.

fb3043d627 Add -fexceptions to Driver 
- Maps to LangOptions.Exceptions
 - Currently always off, should autoselect based on language.

Update CodeGen to set unwind attribute on functions definitions based
       on LangOptions.Exceptions.
 - Still need to set attributes appropriately on calls.

4c3116437c * Remove isInSystemHeader() from DiagClient, move it to SourceManager 
* Move FormatError() from TextDiagnostic up to DiagClient, remove now  
  empty class TextDiagnostic
* Make DiagClient optional for Diagnostic

This fixes the following problems:

* -html-diags (and probably others) does now output the same set of  
  warnings as console clang does
* nothing crashes if one forgets to call setHeaderSearch() on  
  TextDiagnostic
* some code duplication is removed

dcb5e38927 ParseAST now never releases the passed ASTConsumer. This is the responsibility of the client. 
The motivation is that clients may either:

(a) query the ASTConsumer object after AST parsing to collect data/etc.
(b) reuse the ASTConsumer.

2c674f6dbb Refactored driver logic for CodeGen into LLVMCodeGenWriter. This ASTConsumer layers on top of LLVMCodeGen (another existing ASTConsumer) to emit bitcode files to disk. This layering takes this logic out of clang.cpp and puts it directly into the ASTConsumer interface. The benefit is that now --emit-llvm works with both serialized ASTs and regular source files.

4983df37a7 Add more Parser/Sema support for GCC asm-label extension. 
- ActOnDeclarator now takes an additional parameter which is the
   AsmLabel if used. Its unfortunate that this bubbles up this high,
   but we cannot just lump it in as an attribute without mistakenly
   *accepting* it as an attribute.
 - The actual asm-label itself is, however, encoded as an AsmLabelAttr
   on the FunctionDecl.
 - Slightly improved parser error recovery on malformed asm-labels.
 - CodeGen support still missing...

Also added a couple FIXME's since I'm not happy with my fix to Sema. It would be nicer if the super handling for class/instance messages was the same (based on PreDefinedExpr).

return types, and mainly looks at differences in primitive values. The checking
will be expanded in the future.

f0413bfcda Added AnalysisConsumer, a meta-level ASTConsumer class to drive various 
analyses. This potentially is the primordial origins of a Clang-equivalent
"PassManager".

The new AnalysisConsumer interface allows multiple analyses to be run from a
single invocation of Clang.

Migrated the logic of "-warn-dead-stores" and "-warn-uninit-values" to use the
new AnalysisConsumer interface. The new interface results in a significant code
reduction to incorporate an analysis into the Driver.

Updated a test case to (correctly) acknowledge that it contains a dead store
(this check wasn't being performed because it was previously masked by
-warn-uninit-values).

930e099b90 Fix <rdar://problem/5969777> clang ObjC rewriter: #imported file name mysteriously commented out 
This fix involved tightening up needToScanForQualifiers(), which predated ObjCQualifiedIdType.
It also includes a minor tweak to the code that searches for the beginning of the qualified type. If the AST contained the correct beginning of the declaration (i.e. the beginning of the declaration specifiers), this code would be more robust. Since it doesn't, we apply an adhoc heuristic. Note that DeclSpec contains this info...we just don't propagate it to the AST (at present).

14196c099f Implement -rewrite-macros, which is a crazy macro expander that expands 
macros but doesn't expand #includes, remove comments, remove #defines
etc.

For example:

----
#include <stdio.h>

#define bbaa
#define funclike(x) x "a" x "b" x

bbaa  bbaa

#if 1 
funclike("gar")
foo /*blah*/  bar
bar
#endif

#if 0
funclike()
#endif
----


rewrites to:

----
#include <stdio.h>

#define bbaa
#define funclike(x) x "a" x "b" x 

/*bbaa  bbaa*/

#if 1
 "gar" "a" "gar" "b" "gar"/*funclike*//*("gar")*/
foo /*blah*/  bar
bar
#endif

#if 0
/*funclike()*/
#endif

467297ab48 TranslationUnit now owns IdentifierTable, TargetInfo, and Selectors objects 
when it is constructed via deserialization.  This is done by recording a flag
indicating that this is the case, and it deletes these objects by getting
the references stored in the ASTContext object.  This fixes some memory
leaks that occurs when we deserialize translation units from bitcode files.

The rationale between having TranslationUnit sometimes own these objects and
sometimes not is that a TranslationUnit object can be constructed from
state generated by the parser (Preprocessor; semantic analyzer, etc.), and thus
in these cases won't own the IdentifierTable or Selectors, etc.  During
deserialization, there is no Preprocessor, so somebody needs to own these
objects in order for them to be properly reclaimed.
