Improves performance of SynMark OglDrvShComp by +241.879%±1.01366% (n=5)
on a random KBL desktop that I have. That seems to put it at about the
same performance as i965, but I did not test that in a statistically
sound way.

Use the flag that was set by nir_lower_passthrough_edgeflags. The
lowering passes will soon be moved to a finalize_nir hook, so there
won't be any choice. Ideally we'd like to eliminate iris_fix_edge_flags
completely, and this is a first step.

Most modern hardware needs the edge flag added as a hidden vertex input
and needs code added to the vertex shader to copy the input to an
output. Intel hardware is a little different. Gfx4 and Gfx5 hardware
works in the previously described mannter. Gfx6+ hardware needs the
edge flag as a specific vertex shader input, and that input is magically
processed by fixed-function hardware without need for extra shader code.
This flag signals only that the vertex shader input is needed. It would
be nice if we could decouple adding the vertex shader input from
generating the copy-to-output code, but that has proven to be
challenging. Not having that code causes other passes to want to
eliminate that shader input.
v2: Convert conditional to assertion. This pass is only called for
vertex shaders. Suggested by Ken.

**pointer** parameter from brw_nir_lower_storage_image. For some reason

...instead of looking for "ARB" in the name of the shader. This matches
the behavior of i965. Using "ARB" was added in a1ebac3750 ("iris:
Implement ALT mode for ARB_{vertex,fragment}_shader"), but there's no
explanation of why that method was used.
v2: Just use shader_info::is_arb_asm everywhere instead of
iris_uncompiled_shader::use_alt_mode. Suggested by Ken.

No need to re-create this every time we transition from stream-out
enabled to disabled.
Creation of streamout_disable_stateobj is deferred until we create
a program state using streamout to avoid creating it unnecessarily
and because fd6_prog_init() is called before ctx->pipe is created.
(Changing that ordering is complicated by the fact that u_blitter
copies pctx->bind_fs_state(), and friends.)

Some more extreme examples, like gl_driver2_off, can be bottlenecked on
writes to cmdstream. OTOH the CP is pretty pipelined in how it slurps
in memory, so the penalty of using coherent buffers should not be so
much.

It hasn't really mattered until now, as we keep a separate cache for
cmdstream (which is FD_BO_GPU_READONLY), and the only other flag so
far is FD_BO_SCANOUT (which the bo cache probably messes up, but it
does not matter on most hw, and on hw where it does the scanout buffer
will be imported (and therefore won't end up in the bo cache).
But when we add cached-coherent (or if we wanted to use GPU_READONLY
more) it starts to matter.

When moving the batch cache to the context, I added hash table lookups
from batch to rsc for "is this resource in use" because we could no longer
store data in the rsc bo under the batch cache's lock.
We can save that cost by tracking a bitfield of resources referenced by
the batch, which gives us very cheap checks in the draw path at a minor
cost in memory. We can just use the GEM BO handle, since it's a nice
small integer already (we can't use the TC buffer ID, because the frontend
changes that, and we're in the driver thread).
This required moving the !pending() assert up in resource shadowing, since
the BO swap meant we were checking pending on the wrong resource.

I think the whole submit lock thing should be possible to remove now, but
just getting rid of the lock since we're no longer sharing batches between

In moving batch cache to the context, the check for whether there's
pending work being done to this resources ends up accessing the context,
so we can't do it outside of the fd_context_access_begin(). This flag
lets us do the driver-thread asserts before we've decided whether we need
to flush.

This prevents other optimizations from associating the inner multiply,
which can add inaccuracies that can lead to discontinuities around the
boundary of the ffract. We should use exactly the sequence that the blob
uses to avoid problems.
Since fadd + fmul cannot be combined to ffma when exact is specified, we
have to use ffma ourselves.
