* readelf.c (have_frame_base): New.
(need_base_address): Likewise.
(saved_base_address): Likewise.
(decode_location_expression): Return 1 if DW_AT_frame_base is
needed.
(debug_info): Add base_address and a have_frame_base pointer.
(read_and_display_attr_value): Replace saved_DW_AT_low_pc with
saved_base_address. Record base address. Set have_frame_base.
Record if a location list has DW_AT_frame_base. Display if a
location expression has no DW_AT_frame_base but needs one. Set
saved_base_address only if needed.
(process_debug_info): Clear have_frame_base, saved_base_address
and set need_base_address.
(display_debug_loc): Display if a location expression has no
DW_AT_frame_base but needs one. Display if start >= end. Don't
adjust for section address. Properly handle base address.

debug_info.
