Make the precendence order of &,^,| higher than the comparison operators in Pancake

[DoomishGuy]

Made the precendence of the bitwise operators higher than the comparison operators. The last four lines of the following snippet should all now give z=1. The previous precedence order resulted in z=0 in the first line, and z=1 in the other three lines.

fun cmps () {
    var x = 2;
    var y = 3;
    var z = (x & y != 0);
    z = ((x & y) != 0);
    z = (y & x != 0);
    z = ((y & x) != 0);
}
