operators. For example, one can now write "x + y" where x or y is a
class or enumeration type, and Clang will perform overload resolution
for "+" based on the overloaded operators it finds.
The other kinds of overloadable operators in C++ will follow this same
approach.
Three major issues remain:
1) We don't find member operators
2) Since we don't have user-defined conversion operators, we can't
call any of the built-in overloaded operators in C++ [over.built].
3) Once we've done the semantic checks, we drop the overloaded
operator on the floor; it doesn't get into the AST at all.

were being treated as type names for non-Objective-C files.
- Other lines are just because MinimalAction didn't have access to
the LangOptions.

- 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...

- Just added prints for all the action functions. Ideally this would
be extended to print all the information for the actions.

The previous naming scheme was confusing, since it resulted in both the Parser and Action modules having methods with the same name. In addition, the Action module never does any parsing...

void func() {
int xx = xx; // incorrectly diagnosed 'xx' as an undeclared identifier.
}
This smallish bug resulted in a largish fix. Here are some highlights:
- Needed to make sure ParseDeclarator is called *before* parsing any
initializer. Removed the "Init" argument to ParseDeclarator.
- Added AddInitializerToDecl() to the Action & Sema classes.
In Sema, this hook is responsible for validating the initializer and
installing it into the respective decl.
- Moved several semantic checks from ParseDeclarator() to
FinalizeDeclaratorGroup(). Previously, this hook was only responsible for
reversing a list. Now it plays a much larger semantic role.
All of the above changes ended up simplifying ParseDeclarator(), which
is goodness...
