After r12-7931 we again honor MOVE_MAX when folding memcpy to
a load/store pair. On i?86-*-* without SSE this now exposes the
change done in r12-2666-g29f0e955c97da0 which adjusts MOVE_MAX
from 16 to 4 on those targets. This makes adjusting testcases
necessary that assume that we transform memcpy to load/store pairs
on GIMPLE for sizes larger or equal to 8.
Tested on x86_64-unknown-linux-gnu with -m32 -mno-sse.
OK?
