Adds a shared consts base offset and a size of it(dwords) to ir3_compiler
since they might be depending on gpu generations. (Danylo Piliaiev <dpiliaiev@igalia.com> )
Adds a flag to present whether shared consts are enabled to
ir3_shader_options and then it sets to ir3_const_state when creating
an ir3 variant. Although this state is not per-shader state, this is
necessary when figureing out real constlens.
v1. Define a hw quirk for geometry shared const files and use it when
calculating const length.
v2. Don't hardcode when calculating a safe const length.

According to the observation on a630/a650/a660, max_const_pipeline has
to be 512 when all geometry stages are present. Otherwise a gpu hang
happens. Acoordingly maximum safe size for each stage should be under
(max_const_pipeline / 5 (stages)).
Only when VS and FS stages are present, the limit is 640.
v1. Align max_const_safe to 4 vec4's.

This is a huge pain because it's an array, meaning that accessing

the right element stride.
We could always just store the v1 and downconvert if needed... but
this isn't *that* bad that I felt I had to do it that way.

This version of the validator starts adding usage masks into

We're about to lower I/O to scalar, which means we'll end up with
multiple writes to position, and none of them has enough info to
fill in the blanks.
This causes a test that previously crashed on WARP (due to
StoreOutput with an undef not being handled) to fail more
gracefully - but that failure means that the test spends
forever just outputting errors, so explicitly skip it.

First, preprocess the signatures, strictly based on the variables
in the nir shader. Then, later, after the actual shader contents
have been processed, we emit the metadata.
This lets shader processing rely on the pre-processed data (e.g.
the row -> ID mapping needed for large VS inputs) while also allowing
the signature data to rely on data gathered during the shader traversal
(e.g. which components are actually used).

create_vertex_elements_state is sometimes called with a too large

There is no documentation to forbid this practice, so don't rely on

attribute count, which matches the value used to allocate the
descriptors.
Use attributes_read_count rather than attribute_count because the
