Argyrios Kyrtzidis 48dea3b9f5 -getLang().C99 is true in C++ too, remove the use of the C99orCXX variable.
-Scoping in C99 works good for C++ too, remove the C++-specific comments.

If someone thinks that the C++-specific comments are necessary for clarification, let me know and I'll put them back on.

Argyrios Kyrtzidis 857fcc2f8e Add support for C++'s "type-specifier ( expression-list )" expression:
-The Parser calls a new "ActOnCXXTypeConstructExpr" action.
-Sema, depending on the type and expressions number:
   -If the type is a class, it will treat it as a class constructor. [TODO]
   -If there's only one expression (i.e. "int(0.5)" ), creates a new "CXXFunctionalCastExpr" Expr node
   -If there are no expressions (i.e "int()" ), creates a new "CXXZeroInitValueExpr" Expr node.

Daniel Dunbar 12c9ddced1 Change Parser & Sema to use interned "super" for comparions.
- Added as private members for each because it is not clear where to
   put the common definition. Perhaps the IdentifierInfos all of these
   "pseudo-keywords" should be collected into one place (this would
   KnownFunctionIDs and Objective-C property IDs, for example).

Remove Token::isNamedIdentifier.
 - There isn't a good reason to use strcmp when we have interned
   strings, and there isn't a good reason to encourage clients to do
   so.

Daniel Dunbar 56fdb6ae69 More #include cleaning
- Kill unnecessary #includes in .cpp files. This is an automatic
   sweep so some things removed are actually used, but happen to be
   included by a previous header. I tried to get rid of the obvious
   examples and this was the easiest way to trim the #includes in one
   fell swoop.
 - We now return to regularly scheduled development.

Daniel Dunbar 4983df37a7 Add more Parser/Sema support for GCC asm-label extension.
- 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...

Chris Lattner d7352d6801 minor cleanup to the actions interface to pass around SmallVectorImpl instead

@interface NSWhatever : NSObject <NSCopying>

Douglas Gregor 556877c1e6 This patch adds very basic support for parsing and type-checking class
inheritance in C++. It'll parse the base-specifier list, e.g.,

 class D : public B1, virtual public B2 { };

and do some of the simpler semantic checks (B1 and B2 are classes;
they aren't unions or incomplete types, etc).

Chris Lattner 861a226586 This patch is just the easy part of the class names patch, which
allows the parsing of "class" in addition to "struct" and "union" to
declare a record.  So this patch allows:

 class C { };
 class C c1;

But it does not contain the lookup bits, so this won't work yet:

 C c2;

Fariborz Jahanian de615836f3 Patch for:
1) objc ivar processing is split out of ActOnField into its own ActOnIvar method.
2) the new objc ivar action takes visibility info directly, eliminating 
  AllVisibilities in ParseObjCClassInstanceVariables.

Chris Lattner a12405b0ef refactor Parser::ParseStructDeclaration to return a vector of uninterpreted
declarators.  This allows the clients (C structs, objc classes, objc 
properties, [future] C++ classes) etc, to do custom processing before invoking
an action.

This has two benefits in the short term:
1) objc ivar processing should be split out of ActOnField into its own ActOn method.
2) the new objc ivar action can take visibility info directly, eliminating 
   AllVisibilities in ParseObjCClassInstanceVariables.
3) objc properties can pass their own special sauce down to sema as well.
