armv6: Add fetcher for x8r8g8b8 nearest-neighbour transformed images
This is related to the a8r8g8b8 nearest-scaled-cover fetcher. Below are benchmarks for add_x888_8888, which uses it. lowlevel-blt-bench -n : Before After Mean StdDev Mean StdDev Confidence Change L1 12.0 0.0 45.0 0.5 100.0% +275.3% L2 9.2 0.1 30.4 1.2 100.0% +231.6% M 8.6 0.0 27.8 0.1 100.0% +224.0% HT 6.0 0.0 15.4 0.1 100.0% +158.5% VT 5.9 0.0 14.5 0.1 100.0% +146.2% R 5.7 0.0 14.1 0.1 100.0% +145.8% RT 2.9 0.0 5.6 0.1 100.0% +91.4% affine-bench: Before After Mean StdDev Mean StdDev Confidence Change 0.5 12.1 0.0 32.5 0.1 100.0% +169.6% 0.75 11.3 0.0 30.0 0.0 100.0% +165.1% 1.0 10.7 0.0 27.1 0.0 100.0% +153.7% 1.5 9.6 0.0 24.1 0.0 100.0% +151.6% 2.0 8.8 0.0 21.5 0.0 100.0% +145.1%
