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. Differential Revision: https://reviews.llvm.org/D80769
