Massive refactoring around Wasm support

Browse Source 
1. Get rid of old exception handling IR transformer in favor of generation of EH code inside BE
2. Get rid of no-setjmp/longjmp support in C BE
3. Fix various bugs in WebAssembly BE
4. Suppress remaining failing tests for Wasm
5. Enable running Wasm tests by default
