[Pixman] [PATCH 4/4] armv6: enable over_n_8888

[Pekka Paalanen]

From: Pekka Paalanen <pekka.paalanen at collabora.co.uk>

Enable the fast path added in the previous patch by moving the lookup
table entries to their proper locations.

Lowlevel-blt-bench benchmark statistics with 30 iterations, showing the
effect of adding this one patch on top of
"pixman-fast-path: Add over_n_8888 fast path (disabled)",
"pixman-fast-path: enable over_n_8888" and
"armv6: Add over_n_8888 fast path (disabled)".
