Disable trivial pair copy/move tests when unsupported

DimitryAndric · DimitryAndric · commit ca2ab4f657cf · 2016-10-12T20:26:47.000Z
Summary: 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.
