Caio Oliveira d3bdddcf2a spirv: Use NIR_PASS for spirv2nir --optimize 
This allows us to use NIR_DEBUG=print to see each step.
Also use an OPT macro to make code slightly more readable.

Alyssa Rosenzweig 18e19882fa nir: Model AGX-specific multiply-shift-add 
Models `(a * b) + (c << d)` in general, as implemented in various forms on AGX.
This will be fused with backend NIR opt algebraic rules, both for the literal
pattern as well as to strength reduce certain multiplications, e.g. replacing
a * 5 with `a + (a << 2)` expressed as imadshl_agx(a, 1, a, 2).

Alyssa Rosenzweig 0eb5f8e765 nir: Add nir_alu_src_as_uint helper 
We have a few ALU instructions that take a constant source. Technically, they
have a swizzle so you can't just nir_src_as_uint them, even though a bunch of
backends do. To help backends do the right thing, add a helper that's just as
easy to use that will chase the swizzle properly.

Similar to SpvDecorationRestrict, looks like it's also incorrectly

This will allow RADV/CI to leave MESA_SPIRV_LOG_LEVEL as default

When rendering a scaled tile, we need to use the original, hardware
FragCoord when accessing input attachments that are on-tile (i.e. were
rendered to in a previous subpass) because they are also scaled in the
same way that FragCoord is scaled. For input attachments that aren't
already on-tile, however, we need to use the fixed gl_FragCoord. Add a

Caio Oliveira aeec9071b5 spirv: Rework structured control flow handling 
The new code splits the work into a few passes instead of trying to do
everything with a single pass.  This helps to apply the new clarified
rules for structured control flow in the SPIR-V specification, in
particular the "exit construct" rules.

First find an appropriate ordering for the blocks, based on the
approach taken by Tint (WebGPU compiler).  Then, with those blocks
in order, identify the SPIR-V constructs start and end positions.

Finally, walk the blocks again to emit NIR for each of them, "opening"
and "closing" the necessary NIR constructs as we reach the start and
end positions of the SPIR-V constructs.

There are a couple of interesting choices when mapping the constructs
to NIR:

- NIR doesn't have something like a switch, so like the previous code,
  we lower the switch construct to a series of conditionals for each
  case.

- And, unlike the previous code, when there's a need to perform a
  break from a construct that NIR doesn't directly support (e.g. inside
  a case construct, conditionally breaking early from the switch), we
  now use a combination of a NIR loop and an NIR if.  Extra code is
  added to ensure that loop_break and loop_continues are propagated
  to the right loop.

This should fix various issues with valid SPIR-V that previously
resulted in "Invalid back or cross-edge in the CFG" errors.

Thanks to Alan Baker and David Neto for their explanations of
ordering the blocks, in the Tint code and in presentations to
the SPIR-V WG.

Thanks to Jack Clark for providing a lot of valuable tests used to
validate this MR.

Marek Olšák 28374b466c nir: don't remove dead IO variables in nir_lower_io_passes for st_link_nir 
We need to keep variables in the IR because a few places use them,
like nir_build_program_resource_list. This will allow us to lower IO
in the linker.
