Subject: ARM: added 'neon_composite_src_x888_8888' fast path
This fast path function improves performance of 'gnome-system-monitor'
cairo-perf trace.
Benchmark from ARM Cortex-A8 @720MHz
before:
[ # ] backend test min(s) median(s) stddev. count
[ 0] image gnome-system-monitor 68.838 68.899 0.05% 5/6
after:
[ # ] backend test min(s) median(s) stddev. count
[ 0] image gnome-system-monitor 53.336 53.384 0.09% 6/6
