DirectIvarAssignment: Replace vtable'd objects with simple functions.

Avoids unnecessary static constructors.

Add a convenient way to compare GCCVersions without creating temporary objects.

No functionality change.

Only emit debug info for implicit members that actually get codegen, not just ODR use.

This includes special members (copy/default ctor, copy assign, default
ctor) and template specializations for member function templates.

Good for a 5% decrease (1.80 to 1.71 GB) in size on Clang+LLVM's .dwo
files (when using fission).

clang-cl: Don't pass /defaultlib to the linker

Since r187945, clang-cl will add the runtime library dependency to
the .obj file.

Omit  llvm:: before ArrayRef, as we have using llvm::ArrayRef in include/clang/Basic/LLVM.h.

[arcmt] When handling unbridged casts, handle the body of BlockDecl separately because ParentMap does not record
Stmt parent nodes inside a BlockDecl.

Fixes rdar://14686900

Fix for PR16570: when comparing two function pointers, discard qualifiers when
comparing non-reference function parameters.  The qualifiers don't matter for
comparisons.

This is a re-commit of r187769, which was accidentially reverted in r187770,
with a simplification at the suggestion of Eli Friedman.

Expose LambdaIntroducer::DefaultLoc in the AST's LambdaExpr.

Summary:
Source-centric tools need access to the location of a C++11
lambda expression's capture-default ('&' or '=') when it's present.
It's possible for them to find it by re-lexing and re-implementing
rules that Clang's parser has already applied, but the cost of storing
the SourceLocation and making it available to them is 32 bits per
LambdaExpr (a small delta, proportionally), and the simplification in
client code is significant.
