The HW can technically execute 16-bit operations, but the restrictions on 16-bit ALU ops are so great that it ends up not being a win for GLES-on-Vulkan to lower mediump to 16-bit operations, at least with the current state of the Intel compiler. This brings zink-on-anv in line with iris and angle-on-anv for mediump behavior (ANGLE uses RelaxedPrecision, which we ignore).
