id<NSCopyable>*  is not an "objc pointer type", id<NSCopyable> is.

interfaces.  Just because they x->isPointerType() doesn't mean it is
valid to just cast to a pointertype.  We have to handle typedefs etc
as well.

Unify ctx_iterator/ctx_begin()/ctx_end() and iterator/begin()/end() so that a single iterator type is used for both traversing decls of the same declaration context *and* of the parent declaration contexts, depending on the value of the bool parameter 'LookInParentCtx' that is passed to IdentifierResolver::begin().

When in C++, make EnumConstant names hide tag names in the same scope, instead of colliding with them.

- Make sure ObjCIvarDecl propagates the bitfield width.
- RewriteObjC::SynthesizeIvarOffsetComputation(): Avoid using the __OFFSETOF__ mumbo jumbo for bitfields (since it isn't legal C). This fixes <rdar://problem/5986079> clang ObjC rewriter: bitfields and ivar access don't mix.

When checking for name collision between a tag and a previously defined namespace, the collision occured even when the tag was in a different nested scope.
Fix it by taking into account the scope when checking for namespace-tag name collisions.

llvm-svn: 53667

Added parsing/sema support for __attribute__ ((IBOutlet)), a clang-specific attribute that the static analyzer will use to recognize what ivars are IBOutlets.

Add some code to handle vector comparisons, which is the language side
of the llvm vicmp/vfcmp instructions.  Also make the vector-vector and
vector-scalar asign checks a bit more sane under the presence of lax vector
conversions.

1) add a new ASTContext::getFloatTypeSemantics method.
2) Use it from SemaExpr.cpp, CodeGenTypes.cpp and other places.
3) Change the TargetInfo.h get*Format methods to return their 
   fltSemantics byref instead of by pointer.
4) Change CodeGenFunction::EmitBuiltinExpr to allow builtins which
   sometimes expand specially and othertimes fall back to libm.
5) Add support for __builtin_nan("") to codegen, cases that don't pass
   in an empty string are currently lowered to libm calls.
6) Fix codegen of __builtin_infl.

decl attributes out of the various places they can hide.  This makes
us correctly reject things like this:

t.c:2:22: error: mode attribute only supported for integer and floating-point types
  int **__attribute((mode(HI)))* i32;
                     ^

because you can't make a pointer be HImode.
