LLVM IR may be dealing with additional constraints that we don't have in MLIR. For example, I remember fast math flags taking up exactly 7 bits in the instruction encoding.

If we were starting from zero, would we want to put these flags together? Perhaps it would help to see how often each flag like `nneg`/`nsw`/`exact`/`disjoint` appears over the same instruction, or if these are always mutually exclusive
