IIRC this optimization is sometimes important, but it's re-implemented
(in a more sophisticated way) in syntax.el for syntax-ppss, so it would
be good to make the C code somehow use the syntax.el cache.  Maybe the
best way is to change back_comment so that in `lossage' it just calls
a Lisp function (that we'd put in syntax.el), so we can throw away
find_defun_start (and even open_paren_in_column_0_is_defun_start).
