Zoltan Somogyi f345d20e33 Rename X's aux modules as X_helper_N in invalid.
tests/invalid/*.m:
    Rename modules as mentioned above.

    In two cases where the main module name is a Mercury keyword (to the
    extent that Mercury has keywords), add a "test_" prefix to the
    module name.

    Reorganize the ho_default_func_2 test case. The original code
    of this test had three modules, a parent and two children,
    with the module being tested being one of the *child* modules
    (ho_default_func_2.sub). This does not work; the .log file
    from the successful execution of this test case showed that
    there was no actual compilation involved; the test stopped
    after invoking "mmc --generate-dependencies" on that child module.
    The new version of this test makes that child module the main module,
    and moves the relevant parts of the other two original modules
    into a single new child module.

    Rename ii_parent to instance_pc (pc being short for parent-child).
    This test case still has the child module listed as the target
    in Mmakefile, so it still does not progress past generating its
    dependencies.

    Rename the imported_mode test case as bad_exported_mode,
    because this is what it was testing.

    exported_mode.m was used both as the main module of a test,
    and as a helper module in the imported_mode test (now renamed
    to bad_exported_mode). Make a copy of it as a helper module
    for bad_exported_mode.

    Update all references to the moved modules.

    General updates to programming style, such as

    - replacing DCG notation with state var notation
    - adding lines around vim modelines
    - fixing indentation
    - fixing grammar errors in comments
