we can use (u32,u32,u32,u32) to reduce more alignment

I think two u64s is probably as far as I'd want to go with this, rather than e.g. [u8; 16].

Print TypeId as a u128 for Debug
15a6488 
Since <rust-lang#121358>, `TypeId` is
represented as a `(u64, u64)`. This also made the debug implementation a
lot larger, which is especially apparent with pretty formatting.

Change this to convert the inner value back to a `u128` and then print
as a tuple struct to make this less noisy.

Current:

    TypeId { t: (1403077013027291752, 4518903163082958039) }
    TypeId {
        t: (
