This won't regress in this way again, because now the pattern is a
single RTL op.  But yes, target tests for this kind of thing would
be quite useful.

However, I'm going to overhaul the whole SCC thing, so I'd rather
add tests for everything at once.  OTOH, it's a good exercise I
suppose...  Your choice :-)
