Extend Fast_typeops to be a replacement for Typeops

This brings the fix in cad44fc for #2996 to the copy of
Fast_typeops.check_hyps_inclusion.

Fast_typeops.constant_type checks the universe constraints instead of
outputting them. Since everyone who used Typeops.constant_type just
discarded the constraints they've been switched to constant_type_in
which should be the same in Fast_typeops and Typeops.

There are some small differences in the interfaces:
- Typeops.type_of_projection <->
  Fast_typeops.type_of_projection_constant to avoid collision with the
  internally used type_of_projection (which gives the type of [Proj(p,c)]).
- check_hyps_inclusion takes [('a -> constr)] and ['a] instead of
  [constr] for reporting errors.
