glsl: Fix ir validation for bit logic ops

In ir_validate::visit_leave(), the cases for
    - ir_binop_bit_and
    - ir_binop_bit_xor
    - ir_binop_bit_or
were incorrect. It was incorrectly asserted that both operands must be the
same type, when in fact one may be scalar and the other a vector. It was also
incorrectly asserted that the resultant type was the type of the left operand,
which in fact does not hold when the left operand is a scalar and the right
operand is a vector.
