With commit be2990d8fbcd5b4b450e7bfd2053b62d66153b8d
i965: Stop setting LowerBuferInterfaceBlocks
dEQP-GLES31.functional.synchronization.in_invocation.ssbo_alias_overwrite fails
when run through virglrenderer with i965 as GL host.
In the created NIR shaders block 19 a load_ssbo that is present in the nir
created before applying the patch is missing in the version with the patch, and
to me it seems that this is not the result of a proper optimization, because
the value that is read from the ssbo in the older version is replaced by a
literal constant, so I would guess that the real bug is actually in
gl_nior_lower_buffers.</pre>
