Oh, I see. It looks close to what we are trying to do with
https://github.com/llvm/llvm-project/pull/93495, which is:
* create in-memory representations according to the target ABI
* improve efficiency of loads/stores, e.g. load/store of `i18` in LLVM must
touch just 3 bytes, so a compiler would emit one 16-bit load and one 8-bit
load, but if `i18` comes from `_BitInt(18)` then a single 32-bit load would
work better.
