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

WebAssembly: generate load/store Summary: This handles all load/store operations that WebAssembly defines, and handles those necessary for C++ such as i1.

; Test that i1 extending loads and truncating stores are assembled properly.
[WebAssembly] Switch to a more traditional assembly syntax This new syntax is built around putting each instruction on its own line in a "mnemonic op, op, op" like syntax. It also uses conventional data section directives like ".byte" and so on rather than requiring everything to be in hierarchical S-expression format. This is a more natural syntax for a ".s" file format from the perspective of LLVM MC and related tools, while remaining easy to translate into other forms as needed. llvm-svn: 249364
