We were spec-compliant, but rossberg just changed the spec because implementations that hadn't read the spec carefully were non-compliant.

https://github.com/WebAssembly/bulk-memory-operations/pull/118

Because implementations were not in agreement about this and the spec
informally called for src-before-dest, the spec was changed to
correspond to the dynamic and canonical operand order:
dest-before-src. So we adapt to this.
