        * reload.c (find_reloads_address): Make return value tri-state.
        Return -1 if LEGITIMIZE_RELOAD_ADDRESS succeeded.
        (find_reloads): Assume that reloaded addresses match 'o' or
        EXTRA_MEMORY_CONSTRAINT constraints only if find_reloads_address
        returned 1 (not -1).  Omit optional reloads for address operands
        only if find_reloads_address returned 1 (not -1).

Fixes the ICE.
