[Mesa-dev] [PATCH v2 11/21] spirv: Set nir_variable->explicit_binding

[Alejandro Piñeiro]

From: Neil Roberts <nroberts at igalia.com>

When SpvDecorationBinding is encountered in the SPIR-V source it now
sets explicit_binding on the nir_variable. This will be used to
determine whether to initialise sampler and image uniforms with the
binding value.
