This allows shaders to write to storage images declared with unknown
format if they are decorated with NonReadable ("writeonly" in GLSL).
Previously an image view would always use a lowered format for its
surface state, however when a shader declares a write-only image, we
should use the real format. Since we don't know at view creation time
whether it will be used with only write-only images in shaders, create
two surface states using both the original format and the lowered
format. When emitting the binding table, choose between the states
based on whether the image is declared write-only in the shader.
Tested on both Sascha Willems' computeshader sample (with the original
shaders and ones modified to declare images writeonly and omit their
format qualifiers) and on our own shaders for which we need support
for this.

When multiple shader stages exist in the same SPIR-V module, we compile
all entry points and their inputs/outputs, then dead code eliminate the
ones not related to the specific entry point later.
nir_lower_wpos_center was being run prior to eliminating those random
other variables, which made it trip up, thinking it found gl_FragCoord
when it actually found something else like gl_PerVertex[3].

This moves the nir_lower_indirect_derefs() call into
brw_preprocess_nir() so thats is called by both OpenGL and Vulkan
and removes that call to the old GLSL IR pass
lower_variable_index_to_cond_assign()
We want to do this pass in nir to be able to move loop unrolling
to nir.
There is a increase of 1-3 instructions in a small number of shaders,
and 2 Kerbal Space program shaders that increase by 32 instructions.
The changes seem to be caused be the difference in the GLSL IR vs
NIR variable index lowering passes. The GLSL IR pass creates a
simple if ladder for arrays of size 4 or less, while the NIR pass
implements a binary search for all arrays regardless of size.

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.
