Allow implicit pointer/int conversions on ObjCQualifiedIdTypes in Sema::CheckCompareOperands() and Sema::CheckAssignmentConstraints().

Teach Sema::CheckConditionalOperands() to check for ObjCQualifiedIdType's. This fixes a bogus error.

the condidtional have compatible types, they are not necessarily the 
same type.  Therefore, we cast to the composite type.  As a hack, for 
the moment we assume that the composite type is the type of the 
left-hand expression; this isn't correct, but it's good enough for most 
purposes.

expressing the full flexibility of the LLVM shufflevector instruction.  
The expected immediate usage is in *mmintrin.h, so that they don't 
depend on the mess of gcc-inherited (and not completely implemented)
shuffle builtins.

vector of the same element type and half the width, with the high, low, even,
and odd elements respectively.

Allow member references to member references, so that .hi.hi gives you the high
quarter of a vector.  This is fairly convenient syntax for some insert/extract
operations.

Remove some unnecessary methods/types in the ExtVectorElementExpr class.

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.

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.

object type".  Add a predicate that checks exactly this, as it is equivalent
to checking ot see if the type is *not* a function type, which is faster
to check.

First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.

Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.

Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").

This adds an ASTContext::getArrayDecayedType member that handles the 
non-trivial logic for this seemingly simple operation.

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...

Fix objc ivar lookup.  Ivar lookup should occur between lookup
of method-local values and lookup of globals.  Emulate this with
some logic in the handling of Sema::ActOnIdentifierExpr.

Two todo's left:
 1) sema shouldn't turn a bare reference to an ivar into "self->ivar"
    in the AST.  This is a hack.
 2) The new ScopedDecl::isDefinedOutsideFunctionOrMethod method does
    not correctly handle typedefs and enum constants yet.
