glsl: Add lowering pass for ir_bin_imul_high
This isn't the lowering pass you want. Most GPUs that can support GLSL
1.30 have a multiply unit that can do something more interesting than
32x32->32. Many have 32x16->48. Any GPU that does, should do the
lowering in the backend. This is just the thing that will always work.
