I think detecting the GCSE bug can be arbitrarily hairy, and we should
probably just put in the barrier unconditionally.  That is, even on
GCCs that don't have the GCSE bug, we will inhibit some optimizations,
but I think these optimizations aren't important enough to care so
strong about them.

The comment in scm_ithrow can be made more explicit, and we can put an
item in RELEASE to periodically reconsider the issue.
