Wouter van Oortmerssen 2a3fc0c8b2 [WebAssembly] Adding 64-bit versions of all load & store ops.
Context: https://github.com/WebAssembly/memory64/blob/master/proposals/memory64/Overview.md
This is just a first step, adding the new instruction variants while keeping the existing 32-bit functionality working.
Some of the basic load/store tests have new wasm64 versions that show that the basics of the target are working.
Further features need implementation, but these will be added in followups to keep things reviewable.
