Add support for the use of partial module qualifiers,
e.g. using `child:foo' to refer to `parent🧒foo'.
Previously we only allowed names to be fully-qualified
or completely unqualified.
Note that we still don't yet keep track of which modules are visible,
so this change does not properly handle the distinction between
`import_module' and `use_module' declarations for parent modules.
It basically assumes that `child:foo' is allowed iff plain `foo'
would be allowed (i.e. iff `parent:child' has been imported)
whereas it ought to be allowed iff `parent' has been imported.
compiler/modules.m:
Add get_partial_qualifiers/2, for use by make_hlds.m
and hlds_module.m.
compiler/make_hlds.m:
Insert partially-qualified symbols into the cons_table.
compiler/hlds_module.m:
Insert partially-qualified symbols into the pred_table.
compiler/module_qual.m:
When searching the symbol tables used for types, insts, modes,
and typeclasses, search for partially-qualified symbols.
compiler/modecheck_unify.m:
When module-qualifying cons_ids, make sure that we fully module
qualify them even if they're already partially qualified.

tests/hard_coded/parent2.m:
tests/hard_coded/parent2.child.m:
tests/hard_coded/parent2.exp:
Uncomment the previously-failed test of using partially-qualified
symbol names. Add a new child module, `parent.child2', and import it
using `use_module', so that we test `use_module' as well as
`import_module'. Add code to test importing of types and
constructors.
