i965/clip: Removing scissor atom
Now that we no longer use ctx->DrawBuffer->_Xmin and related fields to
program the screen-space viewport extents, we don't depend on any
scissoring state. So we can drop the +_NEW_SCISSOR dependency.
On GEN8, a change in scissor state does not effect anything for the
clipper/sf hardware state. The hardware will always do the right thing
once the viewport extents are programmed. We can therefore remove the
unecessary state emission.
Ken originally spotted this.
v2: Reword the commit message. Remove spurious hunk.
