So, to fix ICE on the following testcase, we can either do what the

does, or could conditionalize both the calculate_dominance_info and
free_dominance_info in the convert_scalars_to_vector function (stv
pass)
on the dominance info not being computed (like other places in gcc do),
or we could stick free_dominance_info into all passes that break the
dominators just in case it would be computed (out_of_cfglayout is one
example).
We rely on this everywhere else so that would be preferred.
So like this instead? Bootstrapped/regtested on x86_64-linux and
i686-linux, ok for trunk?

* cfgrtl.c (cfg_layout_finalize): Free dominators.
* gcc.dg/pr68730.c: New test.
OK.
