Simplify ArrayToPointer conversion. Actually the only thing we need to do is to get the first element region. It is not necessary to care about the kind of the base array region.

First non-embarrassing cut at checking for ambiguous derived-to-base

errors that stem from ambiguous or inacessible base classes. These

Remove the GraphWriter-based version of the C++ class inheritance visualization, since it isn't being used and can't handle virtual bases properly

Fix <rdar://problem/6257675> error: member reference base type ('NSUserDefaults *') is not a structure or union.

Teach Sema::ActOnMemberReferenceExpr() to look through local category implementations associated with the class.

Add representation of base classes in the AST, and verify that we
don't have duplicated direct base classes.

Seriliazation of base class specifiers is not yet implemented.

QualType::isMoreQualifiedThan and isAtLeastAsQualifiedAs assert that we
aren't trying to compare with address-space qualifiers (for now).

Clean up handing of DeclRefExprs in Expr::isLvalue and refactor part
of the check into a static DeclCanBeLvalue.

Implement ranking of standard conversion sequences by their qualification
conversions (e.g., comparing int* -> const int* against
int* -> const volatile int*); see C++ 13.3.3.2p3 bullet 3.

Add Sema::UnwrapSimilarPointerTypes to simplify the control flow of
IsQualificationConversion and CompareQualificationConversion (and fix
the handling of the int* -> volatile int* conversion in the former).

some minor cleanups to ParseObjCTypeName:

1. Remove a bogus assertion, clients other than sema can return a
   null pointer from actions that result in ParseTypeName returning null.
2. Remove dead RParenLoc variable.
3. Simplify control flow handling error conditions.
4. On a major failure, we should skip until ')' not until '}'.
