ipa-cp: Fix check for exceeding param_ipa_cp_value_list_size (PR 113490)
When the check for exceeding param_ipa_cp_value_list_size limit was
modified to be ignored for generating values from self-recursive
calls, it should have been changed from equal to, to equals to or is
greater than. This omission manifests itself as PR 113490.
When I examined the condition I also noticed that the parameter should
come from the callee rather than the caller, since the value list is
associated with the former and not the latter. In practice the limit
is of course very likely to be the same, but I fixed this aspect of
the condition too. I briefly audited all other uses of opt_for_fn in
ipa-cp.cc and all the others looked OK.

callee.
