	(encode_ieee_extended_128, decode_ieee_extended_128): Delete.
	(encode_ieee_extended_motorola, decode_ieee_extended_motorola)
	(encode_ieee_extended_intel_96, decode_ieee_extended_intel_96)
	(encode_ieee_extended_intel_128, decode_ieee_extended_intel_128):
	New functions which convert between 12-byte little-endian Intel
	format and the desired format.
	(ieee_extended_motorola_format, ieee_extended_intel_96_round_53_format)
	(ieee_extended_intel_96_format, ieee_extended_intel_128_format):
