We had defined MAX_IMAGES as 8, which we used to size the array for
image push constant data. The comment there stated that this was for
gen8, but anv_nir_apply_pipeline_layout runs for all gens and writes
that array, asserting that we don't exceed that number of images,
which imposes a limit of MAX_IMAGES on all gens.

Furthermore, despite this, we are exposing up to 64 images per shader
stage on all gens, gen8 included.

This patch lowers the number of images we expose in gen8 to 8 and
keeps 64 images for gen9+. It also sets MAX_IMAGES to 64 so we can
actually use up to 64 images in shaders, and then adds an assert
specific to gen8 to check that we never exceed 8.

v2:
 - <= instead of < in the assert (Eric, Lionel)
 - Change the way the assertion is written (Eric)

I'm not sure why it wasn't < instead of <= previously, sounds like it 
should be <.


Also I don't think this version works, your previous version was okay :


image_count < MAX_GEN8_IMAGE || (gen > 8 && image_count < MAX_IMAGES)

I think <= is fine, map->image_count is not an index but the total
count so its value should be fine up to the maximum allowed, right?

Right, I didn't read Eric's proposal properly, and it would not work
for gen8. I'll revert the form of the assertion to the previous
version.
