mesa/st: provide native integers implementation of ir_unop_any
Previously, ir_unop_any was implemented via a dot-product call, which
uses floating point multiplication and addition. The multiplication was
completely pointless, and the addition can just as well be done with an
or. Since we know that the inputs are booleans, they must already be in
canonical 0/~0 format, and the final SNE can also be avoided.
