* alpha.c (aligned_memory_operand): Recognize the output of
        LEGITIMIZE_RELOAD_ADDRESS.  Examine reg_equiv_memory_loc in
        the event of a pseudo.
        (unaligned_memory_operand): Likewise.  Don't otherwise accept
        completely illegal addresses.
        (normal_memory_operand): Likewise.  Handle subregs of pseudos.
        (get_aligned_mem): Revert previous change.  Abort if we don't have a
        mem.  During reload, call find_replacement on all illegal memories.
        (get_unaligned_address): Likewise.
        * alpha.h (SECONDARY_INPUT_RELOAD_CLASS): Use !aligned_memory_operand
        instead of unaligned_memory_operand.
        * alpha.md: Revert extra argument to get_aligned_mem.
        (reload_inqi): Use any_memory_operand in constraints.  Abort if
        we're not given some sort of mem.
        (reload_inhi): Likewise.
        (reload_outqi, reload_outhi): Likewise.
