Chris Lattner d004505b74 introduce a new ObjCList templated class and start moving 
various objc lists over to it.  First up, the protocol list 
on ObjCInterfaceDecl.

Chris Lattner 87899be4cc when in the context of an @implementation, look for private methods in the 
@implementation to resolve nullary selector references.

Chris Lattner f1c149db9f don't pass in null as the Name for GenerateClassStructure, 
it goes and makes std::strings out of them, which is not 
defined.

Chris Lattner bd2d634424 continue cleaning up code, and disable sending a message directly to an 
interface.  This fixes a bug where we used to accept:

void test2(NSNumber x) {
	[x METH];
}

which doesn't make sense and GCC rejects.

Chris Lattner d7983b472e rename getProtocols -> getProtocol, as it only returns a single 
protocol.  Simplify some code to use unconditional form of the
protocol access list.

Argyrios Kyrtzidis 853fbea313 Replace CurFunctionDecl and CurMethodDecl with methods getCurFunctionDecl() and getCurMethodDecl() that return the appropriate Decl through CurContext.

Ted Kremenek a3a37ae8c8 ObjCMessageExpr objects that represent messages to class methods now can contain the ObjCInterfaceDecl* of the target class if it was available when the ObjCMessageExpr object was constructed. The original interfaces of the class has been preserved (requiring no functionality changes from clients), but now a "getClasSInfo" method returns both the ObjCInterfaceDecl* and IdentifierInfo* of the target class.

Chris Lattner 091f698d29 "this patch adds code generation hooks for Objective-C constant strings. It also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found. This is consistent with Apple GCC. I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it. Possibly there is a way of making the error go away, but I haven't found out what it is yet."

Steve Naroff 25449a5221 Fix <rdar://problem/5986833> clang on xcode: incompatible type returning 'void', expected 'int'. 
- Changed Sema::ObjCActOnStartOfMethodDef() to more accurately type "self" in factory methods.
- Changed Sema::ActOnInstanceMessage() to use the new type to restrict the lookup.

assigned to less protocol qualified object on LHS.

Steve Naroff e643e12313 Tweak Sema::ObjCQualifiedIdTypesAreCompatible() to handle qualified interface types on the RHS. 
This eliminates a bogus warning identified in the test below.

This fixes <rdar://problem/5968256> clang on xcode: error: incompatible type initializing 'NSObject<XCSelectionSource> *', expected 'id<NSObject,XCSelectionSource>'

Chris Lattner 2cc4e23252 Restructure and simplify Sema::ObjCQualifiedIdTypesAreCompatible, 
deleting dead code, making other code more obvious, and fixing a
bug.  This fixes these (bogus) warnings in release mode:

SemaExprObjC.cpp:383: warning: 'RHSProtoE' may be used uninitialized in this function
SemaExprObjC.cpp:383: warning: 'RHSProtoI' may be used uninitialized in this function

Chris Lattner 2a3569b5d9 move ObjCQualifiedIdTypesAreCompatible out of ASTContext into Sema. 
While it is similar to the other compatibility predicates in ASTContext,
it is not used by them and is different.

In addition, greatly simplify ObjCQualifiedIdTypesAreCompatible and
fix some canonical type bugs.  Also, simplify my Type::getAsObjC* methods.

Steve Naroff 2fc93f5c43 Two changes to Sema::LookupDecl() interface. 
(1) Remove IdLoc (it's never used). 
(2) Add a bool to enable/disable lazy builtin creaation (defaults to true).

This enables us to use LookupDecl() in Sema::isTypeName(), which is also part of this commit.

To make this work, I changed isTypeName() to be a non-const member function. I'm not happy with this, however I fiddled with making LookupDecl() and friends const and it got ugly pretty quickly. We can certainly add it back if/when someone has time to fiddle with it. For now, I thought this simplification was more important than retaining the const-ness.

Steve Naroff 257520b1b4 Fairly large "cleaup" related to changing ObjCCompatibleAliasDecl superclass (to inherit from NamedDecl, instead of ScopedDecl). 
- Added a DenseMap to associate an IdentifierInfo with the ObjCCompatibleAliasDecl.
- Renamed LookupScopedDecl->LookupDecl and changed it's return type to Decl. Also added lookup for ObjCCompatibleAliasDecl's.
- Removed Sema::LookupInterfaceDecl(). Converted clients to used LookupDecl().
- Some minor indentation changes.

Will deal with ObjCInterfaceDecl and getObjCInterfaceDecl() in a separate commit...

Chris Lattner 7a51313d8a Make a major restructuring of the clang tree: introduce a top-level 
lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.
