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.

unittests/SupportTests: Add some outs()'s to debug the issues on some bots.
I have run these tests under many configurations on the exact same OS as
the failures, and I can't reproduce them :(.
