Fixing Equality.injectable which did not detect an equality without
constructors as non relevant for injection. Also made injection
failing in such situation.
Incidentally, this fixes a loop in Invfun.reflexivity_with_destruct_cases
(observed in the compilation of CoinductiveReals.LNP_Digit). The
most probable explanation is that this loop was formerly protected by
a failing rewrite which stopped failing after revision 14549 made
second-order pattern-matching more powerful.
Also suppressed dead code in Invfun.intros_with_rewrite.
