 Implement the Strict language extension

 Add a new language extension `-XStrict` which turns all bindings strict
 as if the programmer had written a `!` before it. This also upgrades
 ordinary Haskell to allow recursive and polymorphic strict bindings.

 See the wiki[1] and the Note [Desugar Strict binds] in DsBinds for
 specification and implementation details.
