compiler/hlds_module.m:
compiler/prog_item.m:
Record the identity of predicates and functions that have misplaced
attempts at definition in the interface section using the
pred_pf_name_arity type instead of the pf_sym_name_arity type.
They both specify an arity, but only in pred_pf_name_arity is it clear
*which kind* of arity this is.
compiler/convert_parse_tree.m:
Record external declarations and foreign_procs in the interface
as misplaced attempts at predicate or function definition using
pred_pf_name_arity, so that the code obviously has no arity bugs,
whereas the old code merely had no obvious bugs. (It did actually work.)
Record fact_table pragmas in the interface as similar misplaced attempts
as predicate or function definition, *if* the pragma contains
a pred_or_func indication.
Factor out some common code.
compiler/hlds_pred.m:
Add predicates to return a pred_info's arity as pred_form_arity
and as user_arity.
compiler/make_hlds_separate_items.m:
compiler/typecheck_errors.m:
Conform to the changes above.

tests/invalid_nodepend/foreign_proc_in_interface.{m,err_exp}:
tests/invalid_nodepend/fact_table_in_interface.{m,err_exp}:
Three new test cases to test the

Enable the new tests.

Fix typo in comment.
