target-i386: fix {min,max}{pd,ps,sd,ss} SSE2 instructions
minpd, minps, minsd, minss and maxpd, maxps, maxsd, maxss SSE2 instructions have been broken when switching target-i386 to softfloat. It's not possible to use comparison instructions on float types anymore to softfloat, so use the floatXX_lt function instead, as the float_XX_min and float_XX_max functions can't be used due to the Intel specific behaviour. As it implements the correct NaNs behaviour, let's remove the corresponding entry from the TODO. It fixes GDM screen display on Debian Lenny. Thanks to Peter Maydell and Jason Wessel for their analysis of the problem. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
