glsl: Fix type error when lowering integer divisions
This patch fixes a bug when lowering an integer division: x/y to a multiplication by a reciprocal: int(float(x)*reciprocal(float(y))) If x was a plain int and y was an ivecN, the lowering pass incorrectly assigned the type of the product to be float, when in fact it should be vecN. This caused mesa to abort with an IR validation error. Fixes piglit tests {fs,vs}-op-div-int-ivec{2,3,4}. Reviewed-by: Kenneth Graunke <[email protected]>
