These exist to convert between different types of boolean values. In particular, we want to use these for uniform and shared memory operations where we need to convert to a reasonably sized boolean but we don't care what its format is so we don't want to make the back-end insert an actual i2b/b2i. In the case of uniforms, Mesa can tweak the format of the uniform boolean to whatever the driver wants. In the case of shared, every value in a shared variable comes from the shader so it's already in the right boolean format. The new boolean conversion opcodes get replaced with mov in lower_bool_to_int/float32 so the back-end will hopefully never see them. However, while we're in the middle of optimizing our NIR, they let us have sensible load_uniform/ubo intrinsics and also have the bit size conversion.
