Currently, it is 4 bytes and we do not really need it.
All our targets use 1-byte trap atm.

And sometimes it is inconvenient to have 4 bytes, for example
when we fill gaps with traps in `writeTrapInstr`
and want to fill memory area. (see https://reviews.llvm.org/D44775/https://reviews.llvm.org/D44943).
