The size of this struct depends on the alignment of `u128`, for example powerpc64le and s390x have align-8 and end up with only 280 bytes. Our 64-bit tier-1 arches are the same though, so let's just assert on those.

Not this PR, and I don't know if it's worth bothering, but could try changing the other type to a https://doc.rust-lang.org/nightly/nightly-rustc/rustc_data_structures/packed/struct.Pu128.html so it'd be smaller on x64 too.

Either that, or put #[repr(packed(8))] directly on TokenTypeSet too. I have no idea if there are enough of these being passed around to really matter though.
