isExpensiveCat does not reflect the constraint we have in lowering, which is that the number of unique result elements per thread must be equal to the total number of unique operand elements per thread. This means that we can sometimes fold `CatOp` into layout conversions that have destination layouts that violate this requirement. Rename it to `isLegalCatEncoding` to reflect that it is actually a correctness requirement, and update it to reflect the actual constraint.
Check that the shapes and encodings of CatOp are valid and can be lowered.
