[libc++] Guard terminate_successful with TEST_HAS_NO_EXCEPTIONS
This one is a bit twisted. Some platforms don't have support for exiting in a clean manner, so they don't provide std::exit(). As a result, defining `terminate_successful()` on those platforms won't work, and the PSTL tests that rely on `terminate_successful()` also won't work. However, we don't have a notion of "no clean termination" in libc++, so we can't properly guard this. Since embedded platforms that don't support clean termination usually also don't enable exceptions, we don't need to be able to run those `terminate_successful` PSTL tests, and guarding the definition of `terminate_successful` with TEST_HAS_NO_EXCEPTIONS works pretty well. This is kind of a hack for the lack of having a concept of "no clean termination" in the library and in the test suite. Differential Revision: https://reviews.llvm.org/D153302
