Zoltan Somogyi 3d37c6a442 Report wrongly qualified type names in foreign enums when parsing.
This fixes Mantis bug #486.

compiler/parse_pragma.m:
    Read in the name of the type in a foreign enum in whatever qualified
    form it is in the source code, and then try to implicitly qualify it,
    generating a specific error message if that attempt is unsuccessful.

compiler/parse_sym_name.m:
    To make the above possible, expose the code that does the
    implicit qualification. Do so not just in the form now needed
    by parse_pragma.m, but in the other forms used by other predicates
    in parse_sym_name.m as well, since they probably will be needed
    sooner or later. (The lack of such separated-out capability
    is what led to the code that caused bug 486 in the first place.)

    Avoid an unneeded asymmetry by providing mechanisms to parse
    implicitly qualified sym_names without arguments, as well as
    with arguments.

compiler/parse_util.m:
    Give several of the predicates involved in the above more expressive names.

compiler/parse_inst_mode_defn.m:
compiler/parse_type_defn.m:
compiler/parse_type_repn.m:
compiler/recompilation.check.m:
    Conform to the changes above.

compiler/error_util.m:
    Fix a bug that silently deleted the newly-added simplest_specs,
    which this diff uses for the first time. Add determinism requirements
    to avoid similar problems in the future.

compiler/add_foreign_enum.m:
    Note that the old code that diagnosed attempts to define foreign_enums
    for types in other modules should not be needed anymore.

tests/invalid/foreign_enum_import.err_exp:
    Expect the error message now generated by parse_pragma.m,
    which is more specific than the one generated by add_foreign_enum.m
    until now.

tests/valid/bug486.m:
tests/valid/bug486.window.m:
    A regression test for the bug.

tests/valid/Mmakefile:
    Enable the new test.
