Now we can test C++17 strictly, without enabling removed features.
Fixes D36503.

This improves readability and (theoretically) improves portability,
as _Ugly names are reserved.
This performs additional de-uglification, so all of these tests
follow the example of iterator.traits/empty.pass.cpp.

This makes them consistent (many comments already used uppercase).
The special REQUIRES, UNSUPPORTED, and XFAIL comments are excluded from this change.

Creating a function pointer with proper parameters pointing to std::next() or std::prev() should work.
This change moves the invented paramater for enable_if over to the return type to resolve this QoI issue.

On Apple the test feature 'sanitizer-new-delete' was incorrectly
getting added to the LIT feature set, which mistakenly caused tests
to be disabled when using UBSAN (the feature is only needed with ASAN/MSAN/TSAN).

32-bit powerpc provides a 64 bit time_t type and older ppc64 systems
provide time_t as a floating point type. This caused problems when building
operations.cpp since operations.cpp contained compile time tests for conversions
between time_t and filesystem time type.
When these tests failed they caused the libc++ build to fail as well. This is unfortunate.
This patch moves the tests out of the source file and into the test suite. It also
expands the tests to allow testing of the weird time_t configurations on all platforms.

r283051 added some functions to cmath (in namespace std) that have the
same name as functions in math.h (in the global namespace). Clang's
limited support for `-fdelayed-template-parsing` chokes on this. Rename
the ones in `cmath` and their uses in `complex` and the test.

In order for IDE's like CLion to correctly parse and highlight the tests
it needs to know roughly how to build them. This patch adds a dummy CMake target
for each/all of the .pass.cpp tests in the test suite to solve this problem.
The target is only created when LIBCXX_CONFIGURE_IDE=ON, so it shouldn't affect
most users.
Originally I wasn't sure that this change deserved to live upstream, but it's
quite frustrating to edit libc++ tests using CLion or Visual Studio without it,
in particular the filesystem tests which rely heavily on macros. Even though the change
should have no effect on non-IDE users/configurations I decided to commit it upstream
with the hopes it will benefit somebody other than me.

This patch speculatively implements the PR for LWG 2937, which fixes
two issues with equivalent.
(1) It makes equivalent("dne", "exists") an error. Previously only
equivalent("dne", "dne") was an error and the former case was not (it returned false).
Now equivalent reports an error when either input doesn't exist.
(2) It makes equivalent(p1, p2) well-formed when `is_other(p1) && is_other(p2)`.
Previously this was an error, but there is seemingly no reason why it should be on POSIX system.

This reverts commit r306310.
r306310 causes clang to reject a call to an aligned allocation or
deallocation function if it is not implemented in the standard library
of the deployment target. This is not the desired behavior when users
have defined their own aligned functions.

attribute.
This is needed because older versions of libc++ do not have these
operators. If users target an older deployment target and try to compile
programs in which these operators are explicitly called, the compiler
will complain.
The following is the list of minimum deployment targets for the four
OSes:
macosx: 10.13
ios: 11.0
tvos: 11.0
watchos: 4.0

Clang and C1XX both complain about mismatched class/struct, but libc++ and MSVC's STL
differ on what they use for tuple_element/tuple_size, so there's no way to win here.
I'm reverting this part of my previous change. In the future, I'll have to suppress
the warning for one compiler or the other.

Style/paranoia: 42.1 doesn't have an exact binary representation. Although this doesn't
cause failures, it makes me uncomfortable, so I'm changing it to 42.5.
C1XX rightly warns about unreferenced variables. Adding tests for their values
makes C1XX happy and improves test coverage.
C1XX (somewhat obnoxiously) warns about seeing a struct specialized as a class.
Although the Standard doesn't care, saying struct consistently is better.
(The Standard itself is still inconsistent about whether to depict tuple_element
and tuple_size as structs or classes.)
Fixes D33953.

Remarks: This function shall not participate in overload resolution unless
`is_same_v<decay_t<T>, variant>` is false, unless `decay_t<T>` is
neither a specialization of `in_place_type_t` nor a specialization of
`in_place_index_t`, unless `is_constructible_v<Tj, T>` is true, and
unless the expression `FUN(std::forward<T>(t))` (with `FUN` being the
above-mentioned set of imaginary functions) is well formed.
Depends on D34111.
