We need to inspect the code generated by Ion for wasm on ARM64 and improve it locally when we can; we expect it is a little immature. (For example, constant memory accesses are known to be suboptimal, we need to implement SIMD instruction selection for shuffle, and in general we should vet everything, because the code for ARM64 was moved over quickly from x64 and mips64).

Some experiments, need test cases + some documentation:
- generate much better code for constant-address accesses
- generate better code when storing zero
