[Bug tree-optimization/24026] New: cleanup_control_expr_graph uses fold to fold COND_EXPR_COND

["kazu at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

cleanup_control_expr_graph uses fold to fold COND_EXPR_COND.
It's better to do it at construction time.
I got rid of fold from find_taken_edge once.
Then Diego re-introduced fold in cleanup_control_expr_graph as a fix for PR 23476.
