It seems a little awkward here to do effectively two masks (down to 32 bits for y, then to log2(64) == 6 bits in wrapping_shl), one hidden and one explicit, and have an unwrap-path that may or may not be branch-folded away. It might be a little clearer to just write x << (y & 63), i.e. do the wrapping ourselves? To my eyes at least, it's much less stuff to parse and understand.

(It's also strange and unfortunate that wrapping_shl only takes a u32 amount on a u64 self; I wonder why...)

I believe it takes a u32 on all integer types.

Likewise here, self.ty_mask(ty)

We have a ty_mask function in the ISLE prelude that I think we could delegate to here instead?
