Alyssa Rosenzweig 0aaf174e31 nir/lower_system_values: add ID to 32-bit lowering 
OpenCL has 64-bit global IDs, but for driver-internal OpenCL we only need
32-bit. Might as well lower in nir_lower_system_values instead of bringing up a
whole new pass just for this.

Will be used for asahi precomp

Caterina Shablia a5bcf566a9 nir: lower INSTANCE_{ID,INDEX} to an offset load_instance_{index,id} respectively 
If the hardware does not support INSTANCE_INDEX natively, it will be
lowered to load_instance_id + base_instance. Otherwise, INSTANCE_ID
will be lowered to load_instance_index - base_instance.

Danylo Piliaiev 8482ad0110 nir/nir_lower_is_helper_invocation: Lower helper invocation if required 
nir_lower_is_helper_invocation lowers intrinsic_is_helper_invocation
and uses load_helper_invocation (which is lowered by nir_lower_system_values).
While nir_lower_system_values may lower SYSTEM_VALUE_HELPER_INVOCATION
into intrinsic_is_helper_invocation.

So they depend on each other. Break the dependency by making
nir_lower_is_helper_invocation aware of lower_helper_invocation option
and emitting lowered load_helper_invocation when required.

Happens with SPIR-V 1.6 for which gl_HelperInvocation is translated into
"BuiltIn HelperInvocation" + "Volatile", which nir_lower_system_values
translates into is_helper_invocation.

When the workgroup is 1 dimensional, simply use	a vec3

This is is better than lower_id_to_index + constant folding,
because this way we don't leave behind extra ALU instrs.

Note, this is relevant to mesh shaders on RDNA2 because
it enables us to better detect cross-invocation output
access.

SPV_EXT_demote_to_helper_invocation added OpDemoteToHelperInvocation
operation to turn an invocation into a helper invocation, but the
value of HelperInvocation (a builtin from Input storage class)
couldn't be modified dynamically without breaking compatibility.

For the extension the operation OpIsHelperInvocation was added to get
the dynamic value.

For SPIR-V 1.6, the demote operation was promoted, but now to get the
dynamic value the shader must issue a load to HelperInvocation with
Volatile memory access semantics.

Jason Ekstrand aa4ea9c7ea nir: Add intrinsics for object to/from world RT sysvals 
These are a bit more tricky than most because they're matrix system
values.  We make the intentional choice here to not bother with allowing
indirect addressing of columns for these.  Since they're system values,
they may be magically constructed somehow or come from weird hardware so
it's easier on back-ends to just handle any indirects with bcsel.
