Add a fast path for data constructor workers

See Note [Fast path for data constructors] in
GHC.Core.Opt.Simplify.Iteration

This bypasses lots of expensive logic, in the special case of
applications of data constructors.  It is a surprisingly worthwhile
improvement, as you can see in the figures below.
