Douglas Gregor b53edfb8dc Improve parsing of template arguments to lay the foundation for
handling template template parameters properly. This refactoring:

  - Parses template template arguments as id-expressions, representing
    the result of the parse as a template name (Action::TemplateTy)
    rather than as an expression (lame!).

  - Represents all parsed template arguments via a new parser-specific
    type, ParsedTemplateArgument, which stores the kind of template
    argument (type, non-type, template) along with all of the source
    information about the template argument. This replaces an ad hoc
    set of 3 vectors (one for a void*, which was either a type or an
    expression; one for a bit telling whether the first was a type or
    an expression; and one for a single source location pointing at
    the template argument).

  - Moves TemplateIdAnnotation into the new Parse/Template.h. It never
    belonged in the Basic library anyway.

Evan Cheng e034867587 Change Thumb1 address mode printing, instead of
[r0, #2 * 4]
Now
[r0, #8]

This makes Thumb2 assembly more uniform and frankly the scale doesn't add much.

Daniel Dunbar f76c9d270a Driver: Run 'clang' in C++ mode based on the name it was invoked by. We match
anything that ends with ++ or ++-FOO (e.g., c++, clang++, clang++-1.1) as being
a "C++ compiler".

This allows easy testing of the C++ compiler by 'ln -s clang clang++', or by 'cp
clang clang++'.

Based on patch by Roman Divacky.

Daniel Dunbar b9415c7d9a Add a monstrous hack to improve X86ISelDAGToDAG compile time.
- Force NDEBUG on in any Release build. This drops the compile time to ~100s
   from ~600s, in Release mode.

 - This may just be a temporary workaround, I don't know the true nature of the
   gcc-4.2 compile time performance problem.

Daniel Dunbar be50f5ab9d Localize -disable-llvm-optzns handling to BackendConsumer::CreatePasses.
- This is conceptually better since the only thing we want this option to do is
   preserve the internal module as constructed by IRgen, before running any
   passes.

 - This also fixes bugs in -disable-llvm-optzns handling with regards to debug
   info.

John McCall b8be78b753 Fix a similar problem with qualified lookup through using directives,
although in this case we probably just run a risk of duplicating work;
I can't think of how this could cause a bug.

John McCall 9757d0363d Make a somewhat more convincing test case for unqualified lookup through
using directives, and fix a bug thereby exposed:  since we're playing
tricks with pointers, we need to make certain we're always using the same 
pointers for things.
Also tweak an existing error message.

Zhongxing Xu 537db5d652 SizeofPointerChecker: Many false positives have the form 'sizeof *p'.
This is reasonable because people know what they are doing when they 
intentionally dereference the pointer.
So now we only emit warning when a pointer variable is use literally.

Anders Carlsson ace5d07e50 When trying to assign a regular string literal to an Objective-C 'id' type or a pointer to an NSString, emit a code insertion hint that turns it into an Objective-C string. For example:
@class NSString;

@interface Test
+ (void)test:(NSString *)string;
@end

void g(NSString *a);

void f() {
  NSString *a = "Foo";
  g("Foo");
  [Test test:"Foo"];
}

will produce

t.m:10:17: warning: incompatible pointer types initializing 'char [4]', expected 'NSString *'
  NSString *a = "Foo";
