Roger Ferrer Ibanez aee391b535 Protect bitset tests under libcpp-no-exceptions
Bitset tests feature a sequence of tests of increasing bitset sizes,
but these tests rely on exceptions when the bitset size is less than
50 elements.

This change adds a flag to tell whether a test should throw. If it must
throw it will be skipped under no-exceptions.

Roger Ferrer Ibanez a5672e0c4b Protect std::experimental::optional tests under libcpp-no-exceptions
In these tests there are some paths that explicitly throw, so use
the TEST_THROW macro that was proposed for this and then skip the tests
that may enter the throwing path.

Stephan T. Lavavej 0f901c7ec4 [libcxx] [test] Replace _LIBCPP_STD_VER with TEST_STD_VER.
This replaces every occurrence of _LIBCPP_STD_VER in the tests with
TEST_STD_VER. Additionally, for every affected
file, #include "test_macros.h" is being added explicitly if it wasn't
already there.

Eric Fiselier 0b460e6bf8 Fix __libcpp_is_constructible for source types with explicit conversion operators.
Previously __libcpp_is_constructible checked the validity of reference
construction using 'eat<To>(declval<From>())' but this doesn't consider
From's explicit conversion operators. This patch teaches __libcpp_is_constructible
how to handle these cases. To do this we need to check the validity
using 'static_cast<To>(declval<From>())'. Unfortunately static_cast allows
additional base-to-derived and lvalue-to-rvalue conversions, which have to be
checked for and manually rejected.

While implementing these changes I discovered that Clang incorrectly
rejects `static_cast<int&&>(declval<float&>())` even though
`int &&X(declval<float&>())` is well formed. In order to tolerate this bug
the `__eat<T>(...)` needs to be left in-place. Otherwise it could be replaced
entirely with the new static_cast implementation.

Thanks to Walter Brown for providing the test cases.

Roger Ferrer Ibanez 8a915ed644 Protect exceptional paths under libcpp-no-exceptions
These tests are of the form

try {
   action-that-may-throw
   assert(!exceptional-condition)
   assert(some-other-facts)
 } catch (relevant-exception) {
   assert(exceptional-condition)
 }

Under libcpp-no-exceptions there is still value in verifying
some-other-facts while avoiding the exceptional case. So for these tests
just conditionally check some-other-facts if exceptional-condition is
false. When exception are supported make sure that a true
exceptional-condition throws an exception

Roger Ferrer Ibanez 3565c96d86 Change from "XFAIL: libcpp-no-exceptions" to "UNSUPPORTED: libcpp-no-exceptions" tests that only check exceptions and nothing else
This is a follow up of D24562.

These tests do not check anything but exceptions, so it makes sense to mark
them as UNSUPPORTED under a library built without exceptions.

Eric Fiselier 7ca76565e7 Fix _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY to always have default visibility.
This prevent the symbols from being both externally available and hidden, which
causes them to be linked incorrectly. This is only a problem when the address
of the function is explicitly taken since it will always be inlined otherwise.

This patch fixes the issues that caused r285456 to be reverted, and can
now be reapplied.

Disable the related tests when this define is on, so they don't fail
