* i386.h (i386_regtab): Remove BaseIndex modifier from esp.

	* i386.h: Allow `l' suffix on fld, fst, fstp, fcom, fcomp with
	register operands, because this is a common idiom.  Flag them with
	a warning.  Allow illegal faddp, fsubp, fsubrp, fmulp, fdivp,
	fdivrp because gcc erroneously generates them.  Also flag with a
	warning.

	* i386.h: Add suffix modifiers to most insns, and tighter operand
	checks in some cases.  Fix a number of UnixWare compatibility
	issues with float insns.  Merge some floating point opcodes, using
	new FloatMF modifier.

	consistency.

	IgnoreDataSize where appropriate.

	(COMES_IN_BOTH_DIRECTIONS): Remove.
	(FloatR): Define. It's OK to share the bit with ReverseRegRegmem.

	* config/tc-i386.c (md_assemble): Don't emit operand size prefix
	if IgnoreDataSize modifier given.  Remove ShortformW modifier
	test.  Add test for ShortForm in W base_opcode modification.
