Previously, we were assuming that everything read/wrote exactly 1 logical GRF (1 in SIMD8 and 2 in SIMD16). This isn't actually true. In particular, the PLN instruction reads 2 logical registers in one of the components. This commit changes post-RA scheduling to use regs_read and regs_written instead so that we add enough dependencies.
