* config/tc-m68k.c (m68k_float_copnum): New static variable.

Browse Source 
(md_pseudo_table): Add fopt and mask2.
	(m68k_ip): Use m68k_float_copnum, not COPNUM, when setting
	coprocessor register to use.  In case 'I' when checking operands,
	correct coprocessor register numbers.  In case 'I' when setting
	operands, don't add 1.
	(s_fopt): New static function.
	* config/m68k-parse.h (COPNUM): Don't define.
