virgl: improve virgl_transfer_queue_is_queued

Search only the pending list and return immediately on the first
hit.

When the transfer queue was introduced, the function was used to
deal with

  write transfer -> draw -> write transfer

sequence.  It was used to tell if the second transfer intersects
with the first transfer. If yes, the transfer queue avoided
reordering the second transfer to before the draw (by flushing) in
case the draw uses the transferred data.

With the recent changes to the transfer code, the function is used
to deal with

  write transfer -> readback transfer

We want to avoid reordering the readback transfer to before the
first transfer (also by flushing).

In the old code, we needed to track the compeleted transfers as well
to avoid reordering.  But in the new code, a readback transfer is
guaranteed to see the data from the completed transfers (in other
words, it cannot be reoderered to before the already completed
transfers).  We don't need to search the COMPLETED_LIST.

intel/vec4: Reswizzle VF immediates too

Previously, an instruction like

mul(8) vgrf29.xy:F, vgrf25.yxxx:F, [-1F, 1F, 0F, 0F]

would get rewritten as

mul(8) vgrf0.yz:F, vgrf25.yyxx:F, [-1F, 1F, 0F, 0F]

The latter does not produce the correct result.  The VF immediate in the
second should be either [-1F, -1F, 1F, 1F] or [0F, -1F, 1F, 0F].  This
commit produces the former.

intel/fs: Implement "demote to helper invocation"

The "demote" intrinsic works like "discard" but don't change the
control flow, allowing derivative operations to work.  This is the
semantics of D3D discard.

The "is_helper_invocation" intrinsic will return true for helper
invocations -- both the ones that started as helpers and the ones that
where demoted.  This is needed to avoid changing the behavior of
gl_HelperInvocation which is an input (so not expected to change
during shader execution).

nir: Avoid coalescing vars created by lower_io_to_temporaries

Right now nir_copy_prop_vars is effectively undoing
nir_lower_io_to_temporaries for inputs by propagating the original
variable through the copy created in lower_io_to_temporaries. A
theoretical variable coalescing pass would have the same issue with
output variables, although that doesn't exist yet. To fix this, add a
new bit to nir_variable, and disable copy propagation when it's set.

This doesn't seem to affect any drivers now, probably since since no one
uses lower_io_to_temporaries for inputs as well as copy_prop_vars, but
it will fix radv once we flip on lower_io_to_temporaries for fs inputs.
