- Now Wasm EH uses WinEH instructions (catchswitch, catchpad/ret and cleanupad/ret) - Wasm EH runs WinEHPrepare before WasmEHPrepare, with a flag that it only demotes PHIs in  catchswitch blocks.
- Go back to the previous https://github.com/WebAssembly/exception-handling/blob/master/proposals/Exceptions.md | Wasm EH proposal ]]
- Moved a call to wasm.landingpad.index() intrinsic from invoke blocks to EH pad blocks, which will be more intuitive
- Add DemoteCatchSwitchOnly option to WinEHPrepare for Wasm EH
- Some cosmetic changes
- Rebase
