Marshall Clow 2184374d94 Disable the 'nextafter' portions of these tests on PPC when using 128-bit doubles because the 'nextafter' call doesn't work right. Reviewed as https://reviews.llvm.org/D62384. Thanks to Xing Xue for the patch, and Hubert for the explanation.

Marshall Clow 8dc6840f1c Fix the floating point version of midpoint. It wasn't constexpr, among other things. Add more tests. As a drive-by, the LCD implementation had a class named '__abs' which did a 'absolute value to a common-type' conversion. Rename that to be '__ct_abs'.

Michal Gorny 87ae6bf80b [libc++] [test] Use std::nextafter() instead of std::nexttoward() 
Use std::nextafter() instead of std::nexttoward() in midpoint tests.
In the context of this test, this should not cause any difference.
Since nexttowardl() is not implemented on NetBSD 8, the latter function
combined with 'long double' type caused test failure.  nextafterl() does
not have this problem.
