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
