PR 33914 abort parsing fuzzed .debug_line

The abort is due to an unexpected DW_FORM_addrx3 entry in the
testcase, which requires pointer_size to be known.

	* dwarf.c (address_size_ok): New function.
	(read_debug_line_header): Use address_size_ok.
	(display_formatted_table): Pass li_address_size as
	pointer_size to read_and_display_attr_value.
	(display_debug_lines_decoded): Likewise.
	(display_debug_macro, display_debug_names): Similarly pass
	offset_size.
	(display_loclists_unit_header): Use address_size_ok.
	(display_debug_loc, display_debug_addr): Likewise.
	(display_debug_aranges): Likewise.  Remove power of two check
	on address_size.  Calculate and pad to tuple_size.
