Avoid redundant simplification

When adding specialisation for imported Ids, I noticed that the
Glorious Simplifier was repeatedly (and fruitlessly) simplifying the
same term.  It turned out to be easy to fix this, because I already
had a flag in the ApplyTo and Select constructors of SimplUtils.SimplCont.

See Note [Avoid redundant simplification]
