i965: Stop disabling aux during texture preparation

Previously, we were handling self-dependencies by marking the render
buffer and then passing disable_aux=true to prepare_texture so that it
would do a resolve.  This works but ends us up doing to much resolving
in some cases.  Specifically, if we're doing something such as mipmap
generation, this would cause us to resolve all levels of the texture if
even one of them is overlapping.

Instead, this commit makes us wait until we process the framebuffer to
do these resolves and we only resolve the slices needed for rendering.
Doing this resolve puts them into the pass-through state so, even if we
do texture using CCS_E, the CCS data will effectively be ignored and the
real surface contents read.

The Vulkan spec says:

    "pipelineBindPoint is a VkPipelineBindPoint indicating whether the
    descriptors will be used by graphics pipelines or compute pipelines.
    There is a separate set of bind points for each of graphics and
    compute, so binding one does not disturb the other."

one bind point for everything.  This commit separates things out into

ac/nir: Use instance_rate_inputs per attribute, not per variable.

This did the wrong thing if we had e.g. an array for which only some
of the attributes use the instance index. Tripped up some new CTS
tests.

6 years agoanv: Return trampoline entrypoints from GetInstanceProcAddr

anv: Return trampoline entrypoints from GetInstanceProcAddr

Technically, the Vulkan spec requires that we return valid entrypoints
for all core functionality and any available device extensions.  This
means that, for gen-specific functions, we need to return a trampoline
which looks at the device and calls the right device function.  In 99%
of cases, the loader will do this for us but, aparently, we're supposed
to do it too.  It's a tiny increase in binary size for us to carry this
around but really not bad.

anv: Only advertise enabled entrypoints

The Vulkan spec annoyingly requires us to track what core version and
what all extensions are enabled and only advertise those entrypoints.
Any call to vkGet*ProcAddr for an entrypoint for an extension the client
has not explicitly enabled is supposed to return NULL.
