I noticed that these tests had empty `main` functions. Dropping them and
renaming the tests to `MEOW.compile.pass.cpp` will slightly improve test
throughput.
Three unrelated, small improvements:
* `test_macros.h` was incorrectly saying `__has_include("<version>")`
instead of `__has_include(<version>)`.
+ This caused `<ciso646>` to always be included (noticed because MSVC's
STL emitted a deprecation warning).
+ I searched all of LLVM and found no other occurrences.
* `thread.condition.condvarany/wait_for_pred.pass.cpp` forgot to test
anything.
+ I followed what `wait_for.pass.cpp` is testing.
* Uncomment spaceship test coverage.
We pretty consistently don't define those cause they are not needed,
and it removes the potential pitfall to think that these tests are
being run. This doesn't touch .compile.fail.cpp tests since those
should be replaced by .verify.cpp tests anyway, and there would be
a lot to fix up.
As a fly-by, I also fixed a bit of formatting, removed a few unused
includes and made some very minor, clearly NFC refactorings such as
in allocator.traits/allocator.traits.members/allocate.verify.cpp where
the old test basically made no sense the way it was written.

All supported compilers that support C++20 now support concepts. So, remove
`_LIB_LIBCPP_HAS_NO_CONCEPTS` in favor of `_LIBCPP_STD_VER > 17`. Similarly in
the tests, remove `// UNSUPPORTED: libcpp-no-concepts`.

We never noticed it because our CI doesn't actually build against a C
library that doesn't have threading functionality, however building
against a truly thread-free platform surfaces these issues.
