72bffaafb4 [ADT/IntrusiveRefCntPtr] Give friend access to IntrusiveRefCntPtr<X> so the relevant move constructor can access 'Obj'.

e45100f420 Remove IntrusiveRefCntPtr::getPtr() function 
It was deprecated in r212366 and all uses have been switched to get().

22b4918557 Deprecate IntrusiveRefCntPtr::getPtr() in favour of get() 
This better aligns with other LLVM-specific and C++ standard library smart
pointer types.

In particular there are at least a few uses of intrusive refcounting in the
frontend where it's worth investigating std::shared_ptr as a more appropriate
alternative.

be5c5d7757 Work around MSVC bug in IntrusiveRefCntPtr.h 
The build was failing with:

  error C2664: 'std::atomic_int::atomic_int(const std::atomic_int &)' : cannot convert argument 1 from 'int' to 'const std::atomic_int &'

Apparently "std::atomic_int x(0)" doesn't work, but "std::atomic<int> x(0)"
does.

7fe65d691d Cleanup the simplify_type implementation. 
As far as simplify_type is concerned, there are 3 kinds of smart pointers:

* const correct: A 'const MyPtr<int> &' produces a 'const int*'. A
'MyPtr<int> &' produces a 'int *'.
* always const: Even a 'MyPtr<int> &' produces a 'const int*'.
* no const: Even a 'const MyPtr<int> &' produces a 'int*'.

This patch then does the following:

* Removes the unused specializations. Since they are unused, it is hard
to know which kind should be implemented.
* Make sure we don't drop const.
* Fix the default forwarding so that const correct pointer only need
one specialization.
* Simplifies the existing specializations.

4334dd96a9 Switch LLVM_USE_RVALUE_REFERENCES to LLVM_HAS_RVALUE_REFERENCES. 
Rationale:
1) This was the name in the comment block. ;]
2) It matches Clang's __has_feature naming convention.
3) It matches other compiler-feature-test conventions.

Sorry for the noise. =]

I've also switch the comment block to use a \brief tag and not duplicate
the name.

e3f75f8797 Move-enable IntrusiveRefCntPtr. 
These tend to be copied around a lot, moving it instead saves a ton of memory
accesses.

41aa108f74 RefCountedBaseVPTR needs the IntrusiveRefCntPtrInfo as friend, 
now that this handles the release / retain calls.

Adds a regression test for that bug (which is a compile-time
regression) and for the last two changes to the IntrusiveRefCntPtr,
especially tests for the memory leak due to copy construction of the
ref-counted object and ensuring that the traits are used for release /
retain calls.
