Bug 14610

	* Makefile.in (min-insn-modes.o): Correct dependencies.
	* real.c (encode_ieee_extended, decode_ieee_extended): Always
	produce/consume 12-byte little-endian Intel format.
	(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):
	Update.
testsuite:
	* gcc.dg/ia64-float80-1.c, gcc.dg/ia64-float80-2.c: New testcases.
