Add support for matching '(x & mask) == mask' when mask has a single bit set, and translate this into a tbnz instruction. This patch only does this for 32-bit operations, we can port it to 64-bit operations as a follow-up if we find matches. This transformation mostly touches the snapshot where we get ~120 hits. This pattern can also show up in JavaScript when introduced by the EffectControlLinearizer pass.
