ASTUnit is a helper class to allow easy loading of an ASTContext from a PCH file. No users for now.

C++. This logic is required to trigger implicit instantiation of
function templates and member functions of class templates, which will
be implemented separately.

This commit includes support for -Wunused-parameter, printing warnings
for named parameters that are not used within a function/Objective-C
method/block. Fixes <rdar://problem/6505209>.

Make changes to PCHReader to allow reading a PCH file without having a pre-initialized Preprocessor.

-Introduce 'PCHReaderListener' which is an abstract interface for getting various information from the PCHReader.
-If PCHReader is constructed without a Preprocessor, it can still load the file and invoke the callbacks of PCHReaderListener.
-If PCHReader is constructed with an initialized Preprocessor, PCHValidator is used as a PCHReaderListener to validate the contents of the PCH file against the given Preprocessor.

Add a type (ObjCObjectPointerType) and remove a type (ObjCQualifiedIdType).

This large/tedious patch is just a first step. Next step is to remove ObjCQualifiedInterfaceType. After that, I will remove the magic TypedefType for 'id' (installed by Sema). This work will enable various simplifications throughout clang (when dealing with ObjC types). 

No functionality change.

unnecessary, this was causing issues for assembler-with-cpp mode, which 
doesn't process the directive.

ranges more similar to the console output.  Consider:

#define FOO(X, Y) X/ Y

void foo(int *P, int *Q) {
  FOO(P, Q);
}

Before we emitted:

t.c:4:3:{4:3-4:6}{4:3-4:6}: error: invalid operands to binary expression ('int *' and 'int *')
   FOO(P, Q);
   ^~~~~~~~~
...

Note that while we underline the macro args that the range info just includes FOO 
without its macros.  This change teaches the printed ranges to include macro args
also so that we get:

t.c:4:3:{4:3-4:12}{4:3-4:12}: error: invalid operands to binary expression ('int *' and 'int *')
   FOO(P, Q);
   ^~~~~~~~~
...

It's an error to use a function declared in a class definition as a default argument before the function has been declared.

Note that unlike an earlier revision proposed on cfe-commits, this patch 
still allows declaring block pointers without a prototype.

via -ast-print, -ast-dump, etc., and also via the new member functions
Decl::dump() and Decl::print().
