llvmpipe: improve rasterization discard logic

rasterization disabled logic (which we need for another state tracker),
which really should do the exact same thing.

was entirely pointless.
(We should eventually get rid of implicit discard, which should also
enable us to discard stuff already in draw, hence draw would be
able to skip the pointless clip and fallback stages in this case.)
We still need separate logic for only null ps - this is not the same
as rasterization discard. But simplify the logic there and don't count
primitives simply when there's an empty fs, regardless of depth/stencil

i965: Emit VF cache invalidates for 48-bit addressing bugs with softpin.

We'd like to start using soft-pin to assign BO addresses up front, and
never move them again.  Our previous plan for dealing with 48-bit VF
cache bugs was to relocate vertex buffers to the low 4GB, so we'd never
have addresses that alias in the low 32 bits.  But that requires moving
buffers dynamically.

This patch tracks the last seen BO address for each vertex/index buffer,
and emits a VF cache invalidate if the high bits change.  (Ideally, we
won't hit this case very often.)  This should work for the soft-pin
case, but unfortunately won't work in the relocation case, as we don't
actually know the addresses.  So, we have to use both methods.

v2: Mention that the cache uses a <VertexBufferIndex, Address> tuple
