    Fix bogus RTL on the H8.

    This patch actually fixes the bogus RTL seen in PR101697.

    Basically we continue to use the insn condition to catch most of the
problem
    cases related to autoinc addressing modes.  This patch adds constraints
which
    can guide reload (and hopefully LRA) away from doing blind replacements
during
    register elimination that would ultimately result in bogus RTL.  The id=
ea
is
    from Paul K. who has done something very similar on the pdp11.  I guess=
 it
    shouldn't be a big surprise that the H8 and pdp11 need the same kind of
    handling given some of the similarities in their architectures.
