 Reinstate monomorphism-restriction warnings

 This patch is driven by Trac #10935, and reinstates the
 -fwarn-monomorphism-restriction warning.  It was first lost in 2010:
 d2ce0f52d "Super-monster patch implementing the new typechecker -- at
 last"

 I think the existing documentation is accurate; it is not even
 turned on by -Wall.

 I added one test.
