converting a pointer to one Objective-C interface into a pointer to another
Objective-C interface, and conversions with 'id'. The semantics seems
to match GCC, although they seem somewhat ad hoc.
Fixed a few cases where we assumed the C++ definition of isObjectType,
but were getting the C definition, causing failures in trouble with
conversions to void pointers.

- Other lines are just because MinimalAction didn't have access to
the LangOptions.

- Split backend related consumer out into Backend.cpp, replaces
LLVMCodeGenWriter.
- Structure follows llvm-gcc to some extent.
- Still need to implement all the options which impact code
generation and the optimization passes which llvm-gcc uses at
various levels.

Fix <rdar://problem/6265257> warnings for ambiguous message send swamp other warnings.
Reworked Sema::MatchTwoMethodDeclarations() to optionally match based on method size and alignment (the default in GCC). Changed Sema::LookupInstanceMethodInGlobalPool() to use this feature.
Added -Wno-struct-selector-match to driver, however didn't hook it up yet. Added a FIXME that says this.

after parsing & sema.
- Primarily for timing the impact on -fsyntax-only timings.

- For investigating warnings in system headers / builtins.
- Currently also enables the behavior that allows silent redefinition
of types in system headers. Conceptually these are separate but I
didn't feel it was worth two options (or changing LangOptions).

For example, adding the default system include paths in clients is now as
simple as
InitHeaderSearch init(headers);
init.AddDefaultSystemIncludePaths(langopts);
init.Realize();

- 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.

SourceLocation.h)

* 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

The motivation is that clients may either:
(a) query the ASTConsumer object after AST parsing to collect data/etc.
(b) reuse the ASTConsumer.

clang.cpp now #include these definitions to create the command line options, and
AnalysisConsumer #includes this file to generate the switch statement to create
actions.
Renamed -check-objc-methodsigs to -warn-objc-methodsigs.
The "missing -dealloc" check is now optional: -warn-objc-missing-dealloc

ObjCImplementationDecls and sees if a ancestor class defines a method with the
same selector but with a different type signature. Right now it just compares
return types, and mainly looks at differences in primitive values. The checking
will be expanded in the future.

Renamed -dump-cfg to -cfg-dump, and -view-cfg to -cfg-view. This naming better matches the same options for asts (e.g. -ast-dump).

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).

'There's not much to say about this patch, it just adds the Arch Linux
gcc 4.3.1 header paths for i686 and amd64. The patch was generated
using "svn diff" with clang at revision 52660. The paths aren't
distribution-specific, so they should work for all Linux distributions
using the default(?) names like "i686-pc-linux-gnu".'

'extension that warns by default', which would be cleaner.

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.

clang.cpp: InitializePreprocessor now makes a copy of the contents of PredefinesBuffer and
passes it to the preprocessor object.
clang.cpp: DriverPreprocessorFactory now calls "InitializePreprocessor" instead of this being done in main().
html::HighlightMacros() now takes a PreprocessorFactory, allowing it to conjure up a new
Preprocessor to highlight macros.
class HTMLDiagnostics now takes a PreprocessorFactory* that it can use for html::HighlightMacros().
Updated clients of HTMLDiagnostics to use this new interface.

While this adds no extra functionality now, we will soon pass the
PreprocessorFactory object to some ASTConsumers.

syntax highlighting when we create HTMLDiagnostics in that way.
