[llvm-dev] FreeBSD user willing to try fix a unit test?

[Dimitry Andric via llvm-dev]

Hi Pete,

I tested this on recent FreeBSD 11.0, and indeed the test is now succeeding just fine, as the system compiler is now clang 3.8.0.

Let's just drop the || !defined(__FreeBSD__) part.  Btw, any idea what the defined(__llvm__) part is supposed to accomplish?
