Alex Richardson 0f81598cc1 [libc++] Add a 'is-lockfree-runtime-function' lit feature ... On macOS 10.14 /usr/lib/system/libcompiler_rt.dylib contains all the `__atomic_load*`, etc. functions but does not include the `__atomic_is_lock_free` function. The lack of this function causes the non-lockfree-atomics feature to be set to false even though large atomic operations are actually supported, it's just the is_lock_free() function that is missing. This is required so that the !non-lockfree-atomics feature can be used to XFAIL tests that require runtime library support (D88818).
