Use the stream operation for the SSE2 implementation of memfill32
Writing the data of memfill() to a cacheline is unecessary because the
data is not reused directly. We can use the stream operations to avoid
the cache completely.
When testing memfill32 separately, the function is twice as fast
on Core2 and Atom.
