Move type compatibility predicates from Type to ASTContext. In addition, the predicates are now instance methods (they were previously static class methods on Type).

This allowed me to fix the following hack from this weekend...

// FIXME: Devise a way to do this without using strcmp.
// Would like to say..."return getAsStructureType() == IdStructType;", but
// we don't have a pointer to ASTContext.
bool Type::isObjcIdType() const {
  if (const RecordType *RT = getAsStructureType())
    return !strcmp(RT->getDecl()->getName(), "objc_object");
  return false;
}

...which is now...

bool isObjcIdType(QualType T) const {
  return T->getAsStructureType() == IdStructType;
}

Side notes:

- I had to remove a convenience function from the TypesCompatibleExpr class.

int typesAreCompatible() const {return Type::typesAreCompatible(Type1,Type2);}

Which required a couple clients get a little more verbose...

-    Result = TCE->typesAreCompatible();
+    Result = Ctx.typesAreCompatible(TCE->getArgType1(), TCE->getArgType2());

Overall, I think this change also makes sense for a couple reasons...

1) Since ASTContext vends types, it makes sense for the type compatibility API to be there.
2) This allows the type compatibility predeciates to refer to data not strictly present in the AST (which I have found problematic on several occasions).

Added ASTContext::setObjcIdType/getObjcIdType(), set by Sema.

Also noticed ASTContext::BuiltinVaListType wasn't being initialized to the null type (so I set it).

Teach the type checker about "id". This removes the following bogus warning...

[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang t.m
t.m:29:18: warning: incompatible pointer types assigning 'id' to 'NSString *'
    resultString = [[NSString alloc] initWithFormat:0 arguments:0];

- Teach ObjcInterfaceDecl::lookupInstance/ClassMethod to look through protocols.
- Start looking up methods in the global method pools (for "id").
- Start integrating interface types into the type system.

llvm-svn: 42971

Add category lookup (removing a couple FIXME's).
Changed ObjcInterfaceDecl::ListCategories->CategoryList.

llvm-svn: 42968

Fix -ast-dump for ObjC.

llvm-svn: 42967

- Added Sema::AddFactoryMethodToGlobalPool and Sema::AddInstanceMethodToGlobalPool and DenseMaps. This will allow us to efficiently lookup a method from a selector given no type information (for the "id" data type).

- Fixed some funky "}
                    else {" indentation in Sema::ActOnAddMethodsToObjcDecl(). I'd prefer we stay away from this style...it wastes space and isn't any easier to read (from my perspective, at least:-)

- Changed Parser::ParseObjCInterfaceDeclList() to only call Action::ActOnAddMethodsToObjcDecl() when it actually has methods to add (since most interface have methods, this is a very minor cleanup).

$ clang rewrite.c -rewrite-test
prints:

int foo() {
        b:      foo();
f:      foo();
    foo();
}

for:

int foo() {
	b:	foo();
f:	foo();
    foo();
}

amazing.

width/precision argument was of type 'int'.

Thanks to Anders Carlsson for reporting this missing feature.

ok class names and streamlined this logic to do the lookup once.

Replace one FIXME with another. We handle protocols just fine now. The ObjC decl will only be 0 when we have an error on the ObjC decl. I would prefer we pass in a decl that is marked as invalid. I don't think this is critical to fix now, however I'd like us to be consistent. There are currently many places that don't mark the decl as invalid (which need to be fixed)...
