Display more information when decoding DW_AT_endianity, DW_AT_decimal_sign, DW_AT_defaulted and DW_AT_discr_list DWARF attributes.

	* dwarf.c (read_and_display_attr_value): Handle DW_AT_endianity,
	DW_END_default, DW_END_big, DW_END_little, DW_ATE_UCS,
	DW_ATE_ASCII, DW_CC_pass_by_reference, DW_CC_pass_by_value,
	DW_CC_GNU_renesas_sh, DW_CC_GNU_borland_fastcall_i386,
	DW_AT_decimal_sign, DW_AT_defaulted, DW_AT_discr_list.
	(get_TAG_name): Report user generated tag values.
	* testsuite/binutils-all/dwarf-attributes.S: New test.
	* testsuite/binutils-all/dwarf-attributes.W. Expected output from
	readelf.
	* testsuite/binutils-all/readelf.exp: Run the new test.
