2009-11-22	sh: Add new optimisation to the SH4 memcpy	Austin Foxley
	This optimization is based on prefetching and 64bit data transfer via FPU (only for the little endianess) Tests shows that: ---------------------------------------- Memory bandwidth \| Gain \| sh4-300 \| sh4-200 ---------------------------------------- 512 bytes to 16KiB \| ~20% \| ~25% from 32KiB to 16MiB \| ~190% \| ~5% ---------------------------------------- Signed-off-by: Austin Foxley <austinf@cetoncorp.com> Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
