i965/fs: Copy propagate partial reads.
This commit reworks copy propagation a bit to support propagating the
copying of partial registers. This comes up every time we have pull
constants because we do a pull constant read immediately followed by a move
to splat the one component of the out to 8 or 16-wide. This allows us to
eliminate the copy and simply use the one component of the register.
