Correct, this function was incorrect for systems which have:
#if defined(HAVE_PTHREAD_GET_STACKSIZE_NP) && defined(HAVE_PTHREAD_GET_STACKADDR_NP)

which is where the block is localized.  mono_thread_get_stack_bounds is asking for \
the stack bottom, and we were returning the stack top, which is what \
pthread_get_stackaddr_np does.
