When identifying stacks so as to decide whether or not to make a self
checking translation in the case --smc-check=stack (the default),
don't use SF_GROWDOWN as an indication of stackness, since that only
is set for the main stack. Instead establish whether code is being
taken from a stack by seeing if the requesting thread's stack pointer
points into the same area that the translation is being taken from.
This makes trampolining work even for threaded programs.
