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

don't have duplicated direct base classes.
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.

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).

ASTContext::isObjCObjectPointerType() needs to consider blocks as objects.
Note: My previous commit was done in the test directory...as a result, this commit was necessary.

- Encode unions and bit-fields correctly.
- Accept option to name record fields (used for NeXT runtime).

- Mechanism for detecting if a structure should be expanded wasn't
reliable. Simplified by just keeping track of what we should be
expanding.
- This fixes a bug in using NSInvocation to invoke a method which
returned a structure, which in used by Key Value Observing, which
in the end, caused a miscompile in poor little Sketch.

floats.
- With testcase, which also has some other things GCC folds but we
don't commented out in it.

is to encode the state of the #pragma pack stack as an attribute when
the structure is declared.
- Extend PackedAttr to take an alignment (in bits), and reuse for
both __attribute__((packed)) (which takes no argument, instead
packing tightly (to "minimize the memory required") and for #pragma
pack (which allows specification of the maximum alignment in
bytes). __attribute__((packed)) is just encoded as Alignment=1.
This conflates two related but different mechanisms, but it didn't
seem worth another attribute.
- I have attempted to follow the MSVC semantics as opposed to the gcc
ones, since if I understand correctly #pragma pack originated with
MSVC. The semantics are generally equivalent except when the stack
is altered during the definition of a structure; its not clear if
anyone does this in practice. See testcase if curious.

Instead of using two sets of Decl kinds (Struct/Union/Class and CXXStruct/CXXUnion/CXXClass), use one 'Record' and one 'CXXRecord' Decl kind and make tag kind a property of TagDecl.
Cleans up the code a bit and better reflects that Decl class structure.

When the static type on the Decl side is a subclass of DeclContext the compiler will use a "inlinable" static_cast, instead of always using an out-of-line function call.
Note, though, that the isa<> check still uses an out-of-line function call.

- Modify BlockExpr to reference the BlockDecl.
This is "cleanup" necessary to improve our lookup semantics for blocks (to fix <rdar://problem/6272905> clang block rewriter: parameter to function not imported into block?).
Still some follow-up work to finish this (forthcoming).

This also removes the ugly hack needed in CFG.cpp for subclassing DeclStmt to create a DeclStmt with one Decl*.
