Louis Dionne 31cbe0f240 [libc++] Remove the c++98 Lit feature from the test suite
C++98 and C++03 are effectively aliases as far as Clang is concerned.
As such, allowing both std=c++98 and std=c++03 as Lit parameters is
just slightly confusing, but provides no value. It's similar to allowing
both std=c++17 and std=c++1z, which we don't do.

This was discovered because we had an internal bot that ran the test
suite under both c++98 AND c++03 -- one of which is redundant.

Casey Carter b2e3c83b0d [libc++][test] Miscellaneous MSVC cleanups
* Silence unused-local-typedef warnings: `map.cons/assign_initializer_list.pass.cpp` (and the `set.cons` variant) uses a local typedef only within `LIBCPP_ASSERT`s, so clang diagnoses it as unused when testing non-libc++.
* Add missing include: `c.math/abs.pass.cpp` uses `std::numeric_limits` but failed to `#include <limits>`.
* Don't test non-type: A "recent" change to `meta.trans.other/underlying_type.pass.cpp` unconditionally tests the type `F` which is conditionally defined.
* Use `hash<long long>` instead of `hash<short>` with `int` in `unordered_meow` deduction guide tests to avoid truncation warnings.
* Convert `3.14` explicitly in `midpoint.float.pass` since MSVC incorrectly diagnoses `float meow = 3.14;` as truncating.

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.
