Since all temps allocated by guest front-ends are now TEMP_TB,
and we don't recycle TEMP_TB, there's no point in requiring
that the front-ends free the temps at all. Begin by dropping
the inner-most checks that all temps have been freed.

Using an atomic write or read-write insn on ROM is basically
a happens-never case. Handle it via stop-the-world, which
will generate non-atomic serial code, where we can correctly
ignore the write while producing the correct read result.
