MIPS: DSPr2: Added pixbuf fast path.
Performance numbers before/after on MIPS-74kc @ 1GHz:
lowlevel-blt-bench results
Referent (before):
pixbuf = L1: 18.18 L2: 16.47 M: 13.36 (107.27%) HT: 10.16 VT: 10.07 R: 9.84 RT: 5.54 ( 35Kops/s)
Optimized:
pixbuf = L1: 43.54 L2: 36.02 M: 17.08 (137.09%) HT: 15.58 VT: 14.85 R: 13.87 RT: 8.38 ( 44Kops/s)
