This is a new blitter command introduced on Tigerlake and expanded
substantially on XeHP. XY_BLOCK_COPY_BLT is actually fast, unlike
the legacy blitter commands. iris will use this in the future, and
anv hopefully could use it for a transfer queue someday as well.

We'd like to add safeguards against accidental use of MOCS 0 (uncached),
which can have large performance implications. One case where we use
MOCS of 0 is disabled stream output targets, MOCS shouldn't matter, as
there's no actual buffer to be cached.
That said, it should be harmless to set MOCS for these null stream
output buffers; we can just assume a MOCS for generic internal buffers.

isl now uses info->mocs regardless of whether there's any actual
depth/stencil/HiZ buffers involved, so pass it a legitimate one,
rather than zero. When we have entirely NULL surfaces, we just
default to isl's MOCS value for an internal depth buffer.

The Broadwell PRM says: "Constant Buffer Object Control State must

This patch changes the MOCS field in gen8.xml to be "mbz" type, so that
it's impossible to set it to a non-zero value.

There are some fields which Must Be Zero, and we don't want to allow
setting them from the template struct, but we do want them in the XML
to allow them to be decoded properly, and for documentation purposes.
This adds a new "mbz" type, much like "mbo", except it doesn't set
anything in the struct. We also update the decoder to handle it.

Variable workgroup size works by compiling as much SIMD variants as
possible and then selecting the right one during dispatch (when the
actual workgroup size is passed to us).
Instead of replicating the logic in a separate function, reuse the
same logic for regular SIMD selection. And move function for that
together with the remaining simd selection functions.

Clean up the logic and move it to functions that work with prog_data
attributes to select the right SIMD. This shouldn't change any
behavior compared to the original.
Having it extracted will allow reuse by Task/Mesh and make it easier
to write tests.

Tigerlake revision 0 is an early stepping that should not be used in
production anywhere, so this code was only used for hardware bringup.
We can drop the unnecessary workarounds. This also keeps them from
triggering on early steppings of other Gfx12 parts.

With the `gtest` protocol meson will add some extra arguments to the

protocol is only available in meson 0.55.0+, so keep using the default
`exitcode` protocol for meson older than that.

INTEL_DEBUG is defined (since 4015e1876a) as:
#define INTEL_DEBUG __builtin_expect(intel_debug, 0)
which unfortunately chops off upper 32 bits from intel_debug
on platforms where sizeof(long) != sizeof(uint64_t) because
__builtin_expect is defined only for the long type.
Fix this by changing the definition of INTEL_DEBUG to be function-like
macro with "flags" argument. New definition returns 0 or 1 when
any of the flags match.
Most of the changes in this commit were generated using:
for c in `git grep INTEL_DEBUG | grep "&" | grep -v i915 | awk -F: '{print $1}' | sort | uniq`; do
perl -pi -e "s/INTEL_DEBUG & ([A-Z0-9a-z_]+)/INTEL_DBG(\1)/" $c
perl -pi -e "s/INTEL_DEBUG & (\([A-Z0-9_ |]+\))/INTEL_DBG\1/" $c
done
but it didn't handle all cases and required minor cleanups (like removal
of round brackets which were not needed anymore).
