It shouldn't matter, but the 1 was leftover from when it was handled

The former was always true and hence dead code. We will want to
explicitly declare the ring offset register with ACO, but we also want
to declare the scratch offset too, and we can't try to disable it since
ACO also supports spilling and the determination of whether spilling has
to happen occurs well after setting up registers. So replace
supports_spill with something that will actually be used for ACO.

Due to how LLVM works we have to make some of the FS inputs become
vectors, and therefore have to split them early so that they don't take
up extra register pressure due to how RA currently works.

ac_shader_args will be similar to ac_shader_abi, except for being free
from LLVM-specific concepts and therefore capable of being shared
between LLVM and ACO. This will help us accomplish a few different
things:
- Decouple setting up SGPR and VGPR arguments from translating to LLVM,
so that we can reference these arguments in NIR lowering passes, which
will let us lower e.g. descriptor sets in NIR.
- Stop using radv-specific structures for things like determining the
chip generation in ACO.
In the end, we should replace ac_shader_abi with this structure +
driver-specific lowering passes.

In order to prevent a potential malicious pipeline tainting our
secure compile process and interfering with successive pipelines
we want to create a fresh fork for each pipeline compile.
Benchmarking has shown that simply forking on each pipeline
creation doubles the total time it takes to compile a fossilize db
collection. So instead here we fork the process at device creation
so that we have a slim copy of the device and then fork this
otherwise idle and untainted process each time we compile a
pipeline. Forking this slim copy of the device results in only a
20% increase in compile time vs a 100% increase.
Fixes: cff53da3 ("radv: enable secure compile support")
This will be used to create a communication pipe between the user
facing device and a freshly forked (per pipeline compile) slim copy
of that device.
We can't use pipe() here because the fork will not be a direct fork
of the user facing process. Instead we use a previously forked
copy of the process that was forked at device creation in order to
reduce the resources required for the fork and avoid performance
issues.
Fixes: cff53da374 ("radv: enable secure compile support")
In the following commits we want to be able to fork an existing lightweight
fork created at device creation time. In order for the user facing process
to communicate with this new fresh fork we create some members here to hold
FIFO file descriptors and a unique id.
Here we also add a new fork enum that we use to tell the lightweight
process to create a fresh fork.
For more information on why we create a fresh fork see the following
commits.
