Fix Trac #4874: specialisation of INLINABLE things
Fix Trac #4874: specialisation of INLINABLE things

Johan discovered that when INLINABLE things are specialised
bad things can happen. This patch implements a hack -- but
it's a simple hack and it solves the problem.

See Note [Inline specialisations]. 

The hack part is that really INLINABLE should not cause *any* loss
optimisation, and it does; see Note [Don't w/w INLINABLE things] in
WorkWrap.
