[PATCH] Use $cc instead of $fcc for non-FP coprocessor registers

[PATCH] Use $cc instead of $fcc for non-FP coprocessor registers

[Thiemo Seufer]

Hello All,

I committed the appended patch, it changes the disassembler output of
coprocessor registers used by non-FP instructions from $fcc to $cc.

	* mips-dis.c (print_insn_args): Print $fcc only for FP
	instructions, use $cc elsewise.

... and it needs an additional function argument.
