i965/fs: Create the COPY() set for use in copy propagation dataflow.

This is the "COPY" set from Muchnick's textbook, which is necessary
to do the dataflow algorithm correctly.

v2: Simplify initialization based on Paul Berry's observation that
    out_acp contains exactly what needs to be in the COPY set.
