armv6: Add optimised scanline fetcher for x8r8g8b8
This supports x8r8g8b8 source images.

The before case was using the fetcher iterator defined in pixman-access.c.
Note that it does not appear to be worthwhile to create an additional ARMv7
version of this fetcher. If we construct one using the src_x888_8888 macros
the results are as follows on a Raspberry Pi 2:
