I realised after reading the commentary in subr-x that that's exactly
where it should go -- it is a complement to the C API for interactive
calls.  So, here's my patch to add eval-command-interactive-spec.

Seperately, how about renaming advice-eval-interactive-spec to
eval-interactive-spec, and obsoleting, but not removing, the old name?
I guess that we'd also want to move it to subr.el; this is no promotion,
so far as I can tell, because nadvice.el is preloaded.
