[PATCH] D25449: Disable trivial pair copy/move tests when unsupported

[Dimitry Andric via cfe-commits]

On FreeBSD, for ABI compatibility reasons, the pair trivial copy
constructor is disabled, using the aptly-named
`_LIBCPP_DEPRECATED_ABI_DISABLE_PAIR_TRIVIAL_COPY_CTOR` define.

Disable the related tests when this define is on, so they don't fail
unexpectedly.
