[Mesa-dev] [PATCH] radeonsi/nir: add primitive id to inputs scan

[Timothy Arceri]

Fixes the following piglit tests:

arb_tessellation_shader/fs-primitiveid-instanced
glsl-1.50/primitive-id-no-gs
glsl-1.50/primitive-id-no-gs-first-vertex
glsl-1.50/primitive-id-no-gs-instanced
glsl-1.50/primitive-id-no-gs-strip
glsl-1.50/primitive-id-no-gs-strip-first-vertex
