for bases, members, overridden virtual methods, etc. The operations
isDerivedFrom and lookupInBases are now provided by CXXRecordDecl,
rather than by Sema, so that CodeGen and other clients can use them
directly.

handle checking for a null pointer for a zero-valued
enumerator; moving the test case from CodeGen to Sema.

extension class's protocol list so its AST is complete.
2) Because of this no need to issue warning on unimplemeted
methods coming from the extended class protocols
because warning is issued when class definition is seen.

No functionality change - One less method in Sema:-)

concrete types.  Use unqualified desugaring for getAs<> and sundry.
Fix a few users to either not desugar or use qualified desugar, as seemed
appropriate.  Removed Type's qualified desugar method, as it was easy
to accidentally use instead of QualType's.

"usual deallocation function" with two arguments. CodeGen will have to
handle this case specifically, since the value for the second argument
(the size of the allocated object) may have to be computed at run
time.

value-dependent. Audit (and fixed) all calls to
Expr::isNullPointerConstant() to provide the correct behavior with
value-dependent expressions. Fixes PR5041 and a crash in libstdc++
<locale>.

In the same vein, properly compute value- and type-dependence for
ChooseExpr. Fixes PR4996.

Who would have thought that empty classes were so tricky? Handle cases where an empty virtual base class needs to be moved aside because it conflicts with the first field.

first implementation recognizes when a function declaration is an
explicit function template specialization (based on the presence of a
template<> header), performs template argument deduction + ambiguity
resolution to determine which template is being specialized, and hooks

There are many caveats here:
  - We completely and totally drop any explicitly-specified template
  arguments on the floor
  - We don't diagnose any of the extra semantic things that we should
  diagnose. 
  - I haven't looked to see that we're getting the right linkage for
  explicit specializations

On a happy note, this silences a bunch of errors that show up in
libstdc++'s <iostream>, although Clang still can't get through the
entire header.

Type hierarchy.  Demote 'volatile' to extended-qualifier status.  Audit our
use of qualifiers and fix a few places that weren't dealing with qualifiers
quite right;  many more remain.
