ir3/lower_io_offsets: Try propagate SSBO's SHR into a previous shift instruction
While we lack value range tracking, this patch tries to 'manually' propogate
the division by 4 to calculate SSBO element-offset, into a possible previous
shift operation (shift left or right); checking that it is safe to do so.
This should help in cases like ie. when accessing a field in an array of
structs, where the offset is likely defined as base plus a multiplication
by a struct or array element size.
See dEQP test 'dEQP-GLES31.functional.ssbo.atomic.xor.highp_uint'

ir3/compiler: Enable lower_io_offsets pass and handle new SSBO intrinsics
These intrinsics have the offset in dwords already computed in the last
source, so the change here is basically using that instead of emitting
the ir3_SHR to divide the byte-offset by 4.
The improvement in shader stats is significant, of up to ~15% in
instruction count in some cases. Tested only on a5xx.
shader-db is unfortunately not very useful here because shaders that use
SSBO require GLSL versions that are not supported by freedreno yet.
For examples, most Khronos CTS tests under 'dEQP-GLES31.functional.ssbo.*'
are helped.
A random case:
dEQP-GLES31.functional.ssbo.layout.2_level_array.packed.row_major_mat3x2
with current master:
; CL prog 14/1: 1252 instructions, 0 half, 48 full
; 8 const, 8 constlen
; 61 (ss), 43 (sy)
with the SSBO dword-offset moved to NIR:
; CL prog 14/1: 1053 instructions, 0 half, 45 full
; 7 const, 7 constlen
; 34 (ss), 73 (sy)
The SHR previously emitted for every single SSBO instruction disappears
in most cases, and the dword-offset ends up embedded in the STGB
instruction as immediate in many cases as well.
There are also a few of those tests that are currently failing on register
allocation, that start to pass as a result of reducing the pressure. At least
these, probably more:
dEQP-GLES31.functional.ssbo.layout.random.unsized_arrays.24

For now, it supports lowering the dword-offset computation for SSBO

new ir3-specific version that adds an extra source. That source will
hold the SSA value resulting from inserting a division by 4 (an SHR op)
of the original byte-offset source already provided by NIR in one of
the intrinsic sources.
Note that on a6xx the original byte-offset is not needed, so we could
potentially replace that source instead of adding a new one. But to

st/glsl_to_nir: fix incorrect arrary access
This fixes a segfault when we try to access the array using a

panfrost: Identify fragment_extra flags
The fragment_extra structure contains additional fields extending the
MRT framebuffer descriptor, snuck in between the main framebuffer
descriptor and the render targets. Its fields include those related to
transaction elimination and depth/stencil buffers. This patch identifies
the flags field (previously just "unk" with some magic values) as well
as identifying some (but not all) flags set by the driver.
The process of identifying flags brought a bug to light where
transaction elimination (checksumming) could not be enabled unless AFBC
was in-use. This issue is now resolved.

This implements virtually all documented PIPE_CONTROL restrictions

The hope is that this will fix some intermittent flushing issues as
well as GPU hangs. However, it also has a high risk of causing GPU
hangs and other regressions, as this is a particularly sensitive
area and poking the bear isn't always advisable.
Mark Janes noted that this patch helps with some GPU hangs on Icelake.
This does re-enable the VF Invalidate => Write Immediate workaround
on Gen8, which had been disabled (bug 103787) due to GPU hangs. The
old code did this workaround after another which would have added CS
stall bits, so it missed a workaround. The new code orders them

We may bind new Z/S buffers (which come via the framebuffer CSO,
triggering IRIS_DIRTY_DEPTH_BUFFER), but with writes disabled.
The next draw may enable Z or S writes (which come via the ZSA CSO,
triggering IRIS_DIRTY_WM_DEPTH_STENCIL), which requires us to update
our pin to have the write flag.
So, update pinning if either dirty flag changes. To clarify, pass
cso_zsa to the pinning function rather than pulling the random values
out of ice->state, which unfortunately have to exist for the resolve
code since iris_depth_stencil_alpha_state only exists in iris_state.c.

iris: Refactor depth/stencil buffer pinning into a helper.
This avoids the code duplication that caused me to put things in the
wrong place in the previous commit. One used to have extra flushes,
but we moved those out so now these are identical and can be easily
shared.

iris: Move depth/stencil flushes so they actually do something
Commit
d6dd57d43cd (iris: Add missing depth cache flushes) added the
depth/stencil flushes to the wrong place. I meant to add them to the
iris_upload_dirty_render_state code that emits the packets, but I
accidentally added them to the nearly identical looking code in
iris_restore_render_saved_bos. This meant we missed the actual flushing
at draw time, but instead did pointless flushing on the first draw in a
batch where things are already flushed anyway.
This commit moves them to iris_resolve.c, next to the depth prepares,
similar to what we do for color buffers. i965 does them elsewhere, but
I'm not sure why - this seems like the most consistent place.

iris: Fix TES gl_PatchVerticesIn handling.
1. If we switch the TCS for one with a different number of output
vertices, then the TES's gl_PatchVerticesIn value will change.
We need to re-upload in this case. For now, re-emit constants
whenever the TCS/TES are swapped out.
2. If there is no TCS, then we can't grab gl_PatchVerticesIn from
the TCS info. Since it's a passthrough, we can just use the
primitive's patch count (like the TCS gl_PatchVerticesIn does).
Fixes KHR-GL45.tessellation_shader.single.max_patch_vertices and
KHR-GL45.tessellation_shader.tessellation_control_to_tessellation_evaluation.gl_PatchVerticesIn.

Now that we've added a system value uploading mechanism, we may as well
reuse the same system for default tessellation levels. This simplifies
the state upload code a bit.

iris: Face should be a system value.
This patch adds PIPE_CAP_TGSI_FS_FACE_IS_INTEGER_SYSVAL which
despite its name is not a TGSI-specific capability, just lets
the state tracker know that it should generate a system value
for FACE.
This is needed if we want to run tgsi_to_nir on iris.

That is, drop KHR from all tokens that were promoted to Vulkan 1.1.
The consistency makes ctags more useful (it now jumps directly to the
