Matt Harding bd7ca98b66 Ensure NoTrapAfterNoreturn is false for the wasm backend (#65876) ...

In the WebAssembly back end, the TrapUnreachable option is currently
load-bearing for correctness, inserting wasm `unreachable` instructions
where needed to create valid wasm. There is another option,
NoTrapAfterNoreturn, that removes some of those traps and causes
incorrect wasm to be emitted.

This turns off `NoTrapAfterNoreturn` for the Wasm backend and adds new   
tests.
