Zoltan Somogyi 2bd7c5ee3e Rename X's aux modules as X_helper_N in hard_coded.
tests/hard_coded/*.m:
    Rename modules as mentioned above.

    In a few cases, where the main module's name itself had a suffix,
    such as "_mod_a" or "_main", remove that suffix. This entails
    renaming the .exp file as well. (In some cases, this meant that
    the name of a helper module was "taken over" by the main module
    of the test case.)

    Update all references to the moved modules.

    General updates to programming style, such as

    - replacing DCG notation with state var notation
    - replacing (C->T;E) with (if C then T else E)
    - moving pred/func declarations to just before their code
    - replacing io.write/io.nl sequences with io.write_line
    - replacing io.print/io.nl sequences with io.print_line
    - fixing too-long lines
    - fixing grammar errors in comments

tests/hard_coded/Mmakefile:
tests/hard_coded/Mercury.options:
    Update all references to the moved modules.

    Enable the constant_prop_int test case. The fact that it wasn't enabled
    before is probably an accident. (When constant_prop_int.m was created,
    the test case was added to a list in the Mmakefile, but that list
    was later removed due to never being referenced.)

tests/hard_coded/constant_prop_int.{m,exp}:
    Delete the calls to shift operations with negative shift amounts,
    since we have added a compile-time error for these since the test
    was originally created.
