Interestingly GLSL allows the offset value to be a variable not constant just for the function `textureGatherOffset` while all other offset variants of texture sampling functions require the offset to be a constant value. From a few experiments, I found that the spirv-optimizer changes `Offset` to `ConstOffset` if the offset is a compile-time value. I also found that when the offset value is zero, it changes to `None` with no offset value.
