Fix Trac #2136: reporting of unused variables

There's a bit of a hack RnBinds.rnValBindsAndThen, documented
in Note [Unused binding hack].  But the hack was over brutal
before, and produced unnecssarily bad (absence of) warnings.
This patch does a bit of refactoring; and fixes the bug in
rnValBindsAndThen.
