Lower LLVM's 'unreachable' terminator to ISD::TRAP, and lower ISD::TRAP to wasm's 'unreachable' expression. WebAssembly type-checks expressions, but a noreturn function with a return type that doesn't match the context will cause a check failure. So we lower LLVM 'unreachable' to ISD::TRAP and then lower that to WebAssembly's 'unreachable' expression, which typechecks in any context and causes a trap if executed.
