From: Rob Clark <robclark at freedesktop.org>
Some drivers (well, at least freedreno, maybe others?) need to know
when compiling the shader whether the texture is float/int/unsigned.
This information is in GLSL IR, and in NIR, but lacking in TGSI.
This was previously worked around in the driver by using a shader
variant. But that is annoying and stupid.
