init_mov_optab obsolete?

If EXTRA_CC_MODES is defined, genemit.c writes out a special function
called init_mov_optab that adds entries to mov_optab for patterns that
move those modes around. However, it appears to me that
init_all_optabs (generated by genopinit.c) will set up those entries
anyway.
Am I right, and if so, can we kill it? It's not doing any harm, but
it is confusing when you're trying to unravel what the md processors
do.
(N.B. No current machine description actually defines patterns to move
extra cc modes around.)
