i386 fix

[Jan Hubicka]

Hi
The i386.c attempts to always use reverse_condition on comparison
codes sometimes resulting in UNKNOWN causing it to crash few
function later.

So led  6 22:32:32 CET 2001  Jan Hubicka  <jh@suse.cz>

	* i386.c (ix86_expand_int_movcc): Take care to reverse fp conditions
	properly.
