This clarifies the difference between test for exception support in libc++abi tests and support for exceptions built into libc++abi. This also removes the rather confusing similarity between the _LIBCXXABI_NO_EXCEPTIONS and LIBCXXABI_HAS_NO_EXCEPTIONS macros. Finally, TEST_HAS_NO_EXCEPTIONS is also detected automatically based on -fno-exceptions, so it doesn't have to be specified explicitly through Lit's compile_flags.
