indexXArrayAsY# primops make no attempt at handling alignment
It appears that the unaligned index and store primops added in #14447 (see efd70cfb4b0b9932a880ab417d75eaf95da3d5e6) make no attempt at dealing with architectures that do not permit unaligned memory access. This is currently only problematic when using the LLVM backend to target ARMv7.
