I noticed my initial version might have accidentally changed the behavior for
BE `Vector::reinterpretAsBytes()` and have reverted that part's behavior. Can
you help test again?
Instead of introducing a new benchmark, I introduced a new IR test from the
benchmark in 8391913 and verified it has no potential allocations seen as in
master. I think such an IR test is more resilient. @merykitty can you help
check it out?
