Technically we only have to do late-z in the alpha-test or discard case if depth-write is enabled. If depth write is disabled, the depth read / test / conditional-write interlock that we need to emulate is not a problem, so we can still use early-z test. There is a slightly weird case when there is no zsbuf attachment (see dEQP-GLES31.functional.fbo.no_attachments.*) where the hw wants us to use LATE_Z.. not entirely sure if this is an interaction with occlusion query or just a pecularity of how the hw works when there is no depth buffer.
