Shan Hai afc0a07d4a powerpc/85xx: Fix SPE float to integer conversion failure
Conversion from float to integer should based on both the instruction
encoding and the sign of the operand.

A simple testcase to show the issue:

static float fm;
static signed int si_min = (-2147483647 - 1);
static unsigned int ui;
int main()
{
       fm = (float) si_min; ;
       ui = (unsigned int)fm;
       printf("ui=%d, should be %d\n", ui, si_min);

       return 0;
}
Result: ui=-1, should be -2147483648
