[Pixman] [PATCH] MIPS: DSPr2: Added more fast-paths for OVER operation: - over_8888_n_8888 - over_8888_n_0565 - over_0565_n_0565 - over_8888_8_8888 - over_8888_8_0565 - over_0565_8_0565

From: Nemanja Lukic Performance numbers before/after on MIPS-74kc @ 1GHz: lowlevel-blt-bench results Referent (before): over__n_ = L1: 9.92 L2: 11.27 M: 8.50 ( 45.23%) HT: 4.70 VT: 4.45 R: 4.49 RT: 1.85 ( 20Kops/s) over__n_0565 = L1: 8.95 L2: 8

[Pixman] More MIPS OVER fast paths (over_8888_n_8888, over_8888_n_0565, over_0565_n_0565, over_8888_8_8888, over_8888_8_0565 and over_0565_8_0565).

Added optimizations for several OVER fast paths: - over__n_ - over__n_0565 - over_0565_n_0565 - over__8_ - over__8_0565 - over_0565_8_0565 Benchmark results (lowlevel-blt-bench) on Malta board (@1Ghz) are included in the log message. Any comments to this patch are welc
