Add a vector form of routine vp9_model_rd_from_var_lapndz Add routine vp9_model_rd_from_var_lapndz_vec and call it from model_rd_for_sb to model the rate and distortion for MAX_MB_PLANE Laplacian sources in parallel. The caller ensures that all sources have non-zero variance. Measured a 18% to 25% reduction in retired instructions, and 17% to 24% reduction in instruction execution cost with different compilers for the Laplacian modeling. No change in behavior. TEST=Verified that encoded files match bit for bit, with and without this change. BUG=b/33678225 Change-Id: I6b76947f21c659a349adb896e13e99f6e3f951e6
