Zoltan Somogyi 4398974007 More tweaks to diagnostics. 
compiler/typecheck_errors.m:
    Redo the way we generate diagnostics for unproven typeclass constraints.
    The old approach was: for each type assign (of which there can be many),
    print the list of unproven constraints in that type_assign. Given N
    type assigns, this could print a constraint up to N times.

    This diff switches to a new approach that computes

    - the set of constraints that are unproven in *all* type assigns,
      and which are therefore *definitely* errors, and

    - the set of constraints that are unproven in *some but not all*
      type assigns, which therefore *may be* errors, but also may be
      non-errors,

    and then prints both sets with an explanation of each. Besides the
    classification being helpful to users, telling them which constraints
    to concentrate on fixing first, this approach also guarantees that
    each constraint in its output will appear just once. In other words,
    it has much better worst-case behavior. (Unfortunately, the test suite
    has no test cases that are more complicated than two unproven constraints
    in a single type assign.)

compiler/mark_tail_calls.m:
    Add color to the diagnostics generated by this module.

compiler/add_clause.m:
compiler/check_type_inst_mode_defns.m:
compiler/field_access.m:
    Tweaks to move towards a situation where the messages generated
    for similar errors either in different circumstances or to different
    kinds of entities use the same terminology and use color the same way
    to the extent possible.
