This fixes a bunch of new CTS tests which look for exactly this. Even in
the cases where we just call vk_free to free a CPU data structure, we still
handle NULL explicitly. This way we're less likely to forget to handle
NULL later should we actually do something less trivial.

Here brw_setup_vue_interpolation() is rewritten not to use the InterpQualifier
array in gl_fragment_program which will allow us to remove it.
This change also makes the code which is only used by gen4/5 more self contained
as it now has its own gen5_fragment_program struct rather than storing the map
in brw_context. This means the interpolation map will only get processed once
and will get stored in the in memory cache rather than being processed everytime
the fs changes.
Also by calling this from the fs compile code rather than from the upload code
and using the interpolation assigned there we can get rid of the
BRW_NEW_INTERPOLATION_MAP flag.
It might not seem ideal to add a gen5_fragment_program struct however by the end
of this series we will have gotten rid of all the brw_{shader_stage}_program
structs and replaced them with a generic brw_program struct so there will only
be two program structs which is better than what we have now.
V2: Don't remove BRW_NEW_INTERPOLATION_MAP from dirty_bit_map until the following
patch to fix build error.
V3 - Suggestions by Jason:
- name struct gen4_fragment_program rather than gen5_fragment_program
- don't use enum with memset()
- create interp mode set helper and simplify logic to call it
- add assert when calling function to show prog will never be NULL for
gen4/5 i.e. no Vulkan

The original pipeline cache the Kristian wrote was based on a now-false
premise that the shaders can be stored in the pipeline cache. The Vulkan
1.0 spec explicitly states that the pipeline cache object is transiant and
you are allowed to delete it after using it to create a pipeline with no
ill effects. As nice as Kristian's design was, it doesn't jive with the
expectation provided by the Vulkan spec.
The new pipeline cache uses reference-counted anv_shader_bin objects that
are backed by a large state pool. The cache itself is just a hash table
mapping keys hashes to anv_shader_bin objects. This has the added
advantage of removing one more hand-rolled hash table from mesa.

The hardware packets organize kernel pointers and GRF start by slots that

This commit reworks and simplifies the way we handle persample shading in
the shader key and prog_data. The previous approach had three different
key bits that had slightly different and hard-to-decern meanings while the
new bits are far more clear. This commit changes it to two easily
understood bits that communicate everything we need:
1) key->persample_interp: means that the user has requested persample
interpolation through the API. This is equivalent to having
SAMPLE_SHADING enabled and having MIN_SAMPLE_SHADING_VALUE set high
enough that you actually get multiple per-sample invocations.
2) key->multisample_fbo: means that the shader will be running on an
actual multi-sampled framebuffer.
This commit also adds a new "persample_dispatch" bit to prog_data which
indicates that the shader should be run in persample mode. This way the
state setup code doesn't have to look at the fragment program or GL state
and can just pull that data out of the prog_data.
In theory, this shuffle could mean more recompiles. However, in practice,
we were shoving enough state into the key before that we were probably
hitting a recompile on every per-sample shader anyway.
