Fix deriving Ord when RebindableSyntax is enabled
Deriving clauses (Ord especially) generated if-expressions with nlHsIf
which were subject to RebindableSyntax. This changes nlHsIf to generate
concrete if-expressions.
There was also an error about calling tagToEnum# at a polymorphic type,
which is not allowed. Fixing nlHsIf didn't fix this for some reason, so
I generated a type ascription around the call to tagToEnum#. Not sure
why the typechecker could not figure this out.
Test Plan: Added a test, ran validate.
