    * cfgexpand.c (convert_debug_memory_address): Add AS parameter.
    Use target address_mode and pointer_mode hooks instead of hardcoded
    Pmode and ptr_mode.  Handle some simple cases of extending if
    POINTERS_EXTEND_UNSIGNED < 0.
    (expand_debug_expr) <case MEM_REF, INDIRECT_REF, TARGET_MEM_REF>:
    Call convert_debug_memory_address.
    (expand_debug_expr) <case ADDR_EXPR>: Pass as to
    convert_debug_memory_address.
