This can be useful to measure whether memory access optimizations are
having the desired effect. For example, we might see a reduction in
image loads/stores, or constant buffer loads. We can already see this
in cycle estimates to some extent, but this is a more direct approach,
minus a lot of the noise of random scheduler shuffling.

DPH isn't actually commutative, so this doesn't work. If the immediate

This function was difficult to implement for new formats due to the
combination of endianness and swapbytes support. Since it's mostly
used for fast paths, bugs in it were often missed during testing.
Just reimplement it on top of the recent
_mesa_format_from_format_and_type() which can give us a canonical
MESA_FORMAT for a format and type enum (while respecting endianness).
Fixes:
- R4G4B4A4_UNORM, B4G4R4_UINT, R4G4B4A4_UINT incorrectly matched with
swapBytes (you can't just reverse the channels if the channels
aren't bytes)
- A4R4G4B4_UNORM and A4R4G4B4_UINT missing BGRA/4444_REV matches
- failing to match RGB/BGR unorm8 array formats on BE
- 2101010 formats incorrectly matching with swapBytes set.
- UINT/SINT byte formats failed to match with swapBytes set.
This deletes the part of tests/mesa_formats.cpp that called
_mesa_format_matches_format_and_type() to make sure it didn't
assertion fail, as it now would assertion fail due to the fact that we
were passing an invalid format (GL_RG) for most types.

In desktop GL, you can specify things like GL_DEPTH_COMPONENT/GL_BYTE as a
ReadPixels format, and we need to be able to represent that to see if we
have proper MESA_FORMATs for them. That's exactly what the
mesa_array_format enum is for.
v2: Drop _mesa from static fn.

We had missed this case where GLES3 allows glReadPixels(DEPTH, UINT_24_8),
and just got lucky by the readpixels path never asking for the matching
format from this function.

The GL spec says the 24-bit component is in the high bits, and
format_unpack.c looks at the high 24 bits in the S8Z24 case, not
Z24SS8.

When used in a GS pipeline, the VS doesn't end with the END
instruction. Instead it chains to the GS, which continues running with
the same register allocation. The intended use cases seems to be that
you can compile a regular VS (ie outputs in registers and ending with
END) but then tack on link-time generated code past the END to write
the outputs using STLW, in case the VS is used with GS.

We don't know what kind of loads we might have to wait on when coming

These sysvals have to be unclobbered by VS and in the same registers
in both VS and GS, since the chsh from VS to GS doesn't reload the
values. We use the pre-color argument to ir3_ra() to always place
these values in r0.x and r0.y.

Inputs are the GS header, which contains vertex ID, local primitive ID
and thread ID as well as primitive ID. The setup is a little different
from other sysvals, since we always have to receive them in the VS so
that it can pass them on into the GS.
The vertex flag outputs from GS is set up as a proper nir output in
the lowering pass and doesn't need special handling here.
