i965: Add nir based intrinsic lowering and thread ID uniform
We add a lowering pass for nir intrinsics. This pass can replace nir intrinsics with driver specific nir lower code. We lower the gl_LocalInvocationIndex intrinsic based on a uniform which is loaded with a thread specific ID. We also lower the gl_LocalInvocationID based on gl_LocalInvocationIndex. v2: * Create variable during lowering pass. (Ken) v3: * Don't create a variable, but instead just insert an intrisic call to load a uniform from the allocated location. (Jason) v4: * Don't run this pass if thread_local_id_index < 0 Cc: "12.0" <[email protected]> Signed-off-by: Jordan Justen <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>
