pointer-to-base. Also, add overload ranking for pointer conversions
(for both pointer-to-void and derived-to-base pointer conversions).
Note that we do not yet diagnose derived-to-base pointer conversion
errors that stem from ambiguous or inacessible base classes. These
aren't handled during overload resolution; rather, when the conversion
is actually used we go ahead and diagnose the error.

Mea culpa: I introduced this regresson in the following 2 commits: r57529 (10/14), r57841 (10/20).

Factored the QualTypeOrdering predicate into its own header
(TypeOrdering.h), now that it is used in two places.

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

Seriliazation of base class specifiers is not yet implemented.

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.

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).

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 '}'.

- Split backend related consumer out into Backend.cpp, replaces
LLVMCodeGenWriter.
- Structure follows llvm-gcc to some extent.
- Still need to implement all the options which impact code
generation and the optimization passes which llvm-gcc uses at
various levels.

Changes:
- Sema::IsQualificationConversion determines whether we have a qualification
conversion.
- Sema::CheckSingleAssignment constraints now follows the C++ rules in C++,
performing an implicit conversion from the right-hand side to the type of
the left-hand side rather than checking based on the C notion of
"compatibility". We now rely on the implicit-conversion code to
determine whether the conversion can happen or
not. Sema::TryCopyInitialization has an ugly reference-related
hack to cope with the initialization of references, for now.
- When building DeclRefExprs, strip away the reference type, since
there are no expressions whose type is a reference. We'll need to
do this throughout Sema.
- Expr::isLvalue now permits functions to be lvalues in C++ (but not
in C).
