[Pixman] Several MIPS fast paths.

Added optimizations for several out_reverse, over_reverse and in oprations: - out_reverse_8_0565 - out_reverse_8_ - over_reverse_n_ - in_n_8_8 Benchmark results (lowlevel-blt-bench) on Malta board (@1Ghz) are included in the log messages. Any comments to these patches are

[Pixman] [PATCH 1/2] MIPS: DSPr2: Added more fast-paths for REVERSE operation: - out_reverse_8_0565 - out_reverse_8_8888
