Fix Trac #1402: typo in specialiser

This patch fixes a plain bug in the specialiser (rhs_bndrs instead
of rhs_ids) which made GHC crash in obscure cases.

It exposed a case in which we might not do all possible specialisation;
see Note [Specialisation shape].  It's not an important case, but I've
added a warning in DEBUG mode.

Trac #1402.  Test is spec003.hs
