Revert r216497: "[libcxx] Fix ctype_byname<wchar_t>::do_is() mask checking."

After discussing implementing more tests for this with @danalbert & @mclow, I
realized this change is not correct.

The C++ standard requires do_is() to behave as if it were a loop that checked
is(). Furthermore, it requires is() to check "The first form returns the result
of the expression (M & m) != 0; i.e., true if the character has the
characteristics specified"... which the reverted patch definitely does not
conform to. Even further, furthermore, this requires that ctype's mask be an
actual bitmask, unlike what android and newlib provide for _ctype_.

Fixing the original bug that instigated this patch remains TBD.

Mark test types for <atomic> nothrow default constructible. Patch from Steve MacKenzie.

The way the standard currently specifies the default constructor for atomic<T>
requires T to be nothrow default constructible. This patch makes our test types
meet this requirement.

Note: The nothrow default constructible requirment is subject to the outcome of
LWG issue 1265.

test: Allow using clang -verify for failures rather than exit 1

Currently, failure tests work by checking that compilation exits 1.
This can lead to tests that fail for the wrong reason, so it'd be
preferable to convert them to check for specific errors.

This adds use_clang_verify parameter that runs failure tests using
clang's -verify flag. I'll convert some tests in subsequent commits,
and once all of the tests are converted we should key this on whether
cxx_under_test is clang.

I've also converted one of the unique.ptr tests, since it's the one
that motivated the idea of using clang -verify when possible in the
review of r216317.

test: Make it possible to opt in to use_clang_verify per test

This modifies the use_clang_verify parameter I added in r217009 to
only apply to tests that specifically ask for it via // USE_VERIFY.
This allows us to incrementally convert tests, but start enjoying the
benefits right away.

Suggested by Eric Fiselier in code review.
