I've coded up a fix to mww where it uses target_write_buffer()
instead of target_write_memory(). This promises to be orders
of magnitudes faster for filling large memory areas(e.g.
with garbage before running some test).

target_write_buffer() is documented to transform to
target_write_memory() for single word aligned writes.

It doesn't work yet.

Any fundamental objections?
