Fixes to allow testing of `ground' matches `bound'.
compiler/modules.m:
When writing discriminated union types to the .int2 file, write
out the full type definition rather than an abstract type
declaration. This is necessary because a module which
transitively imports the .int2 file may need to know the
constructors to allow `ground' to be compared with `bound'
insts. See the new test case `transitive_inst_type' for an
example. If the type has user-defined equality and/or comparison
predicates then we write "... where type_is_abstract_noncanonical"
to the .int2 file instead of giving the predicate names.
compiler/make_hlds.m:
If a discriminated union type is imported from a .int2 file, mark it
as `abstract_imported'.
compiler/typecheck.m:
When type checking var-functor unifications, do not allow functors
whose types are `abstract_imported', unless we are type checking an
`opt_imported' predicate.
compiler/prog_data.m:
Add a new alternative `abstract_noncanonical_type' to the type
`unify_compare' to represent "where type_is_abstract_noncanonical"
annotations read from .int2 files.
compiler/prog_io.m:
Parse "where type_is_abstract_noncanonical" annotations on
discriminated union types.
compiler/special_pred.m:
compiler/unify_proc.m:
Avoid creating unification and comparison predicates
for types with `type_is_abstract_noncanonical' annotations.
compiler/intermod.m:
Handle the change to the `unify_compare' type.
compiler/type_util.m:
Do not remove module qualifiers from constructors before looking
them up in the cons table. Some cons ids only have the
qualified version in the table.
