Fix the process of getting the ObjC runtime - if we ask for it too early (in the process of handling the
load notification for the first load) then we will set it the runtime to NULL and won't re-search for it.
Added a way for the dynamic loader to force a re-search, since it knows the world has changed.

We do not reanalyze a function, which has already been analyzed as an

* Add enums and structures for GNU version information.
* Implement extraction of that information on a per-symbol basis (ELFObjectFile::getSymbolVersion).
* Implement a generic interface, GetELFSymbolVersion(), for getting the symbol version from the ObjectFile (hides the templating).
* Have llvm-readobj print out the version, when available.
* Add a test for the new feature: readobj-elf-versioning.test

When an error made a record member invalid, the record would stay as "isBeingDefined" and
not "completeDefinition". Even easily recoverable errors ended up propagating records in
such "beingDefined" state, for example:

struct A {
  ~A() const; // expected-error {{'const' qualifier is not allowed on a destructor}}
};
struct B : A {}; // A & B would stay as "not complete definition" and "being defined".

This weird state was impending lookups in the records and hitting assertion in the ASTWriter.

 - The theory here is that we have these functions sprinkled in all over the
   place. This should allow the optimizer to at least realize it can still do
   load CSE across these calls.
 - I blindly marked all instances as such, even though the optimizer can infer
   this attribute in some instances (some of the inline ones) as that was easier
   and also, when given the choice between thinking and not thinking, I prefer
   the latter.

You might think this is mere frivolity, but actually this is good for a .7 -
1.1% speedup on 403.gcc/combine.c, JSC/Interpreter.cpp,
OGF/NSBezierPath-OAExtensions.m.

 - getSourceRange().getBegin() is about as awesome a pattern as .copy().size().

I already killed the hot paths so this doesn't seem to impact performance on my
tests-of-the-day, but it is a much more sensible (and shorter) pattern.
