* Implement throw & catch statements (#6916)Julius Ikkala2025-05-23

To make SPIR-V happy. * Fix dead catch blocks and invalid cached dominator tree * More SPIR-V adjustment * Lower catch as two nested loops * Add defer interaction test and revert broken defer changes * Fix enum type when throwing literals * Cleanup and bikeshedding * Document error handling mechanism * Fix table of contents * Use boolean tag in Result<T, E> * Use anyValue storage for Result<T,E> * Remove IError * Fix formatting * Eradicate success values from docs and tests * Use parseModernParamDecl for catch parameter * Implement do-catch syntax * Implement catch-all * Fix formatting * Fix marshalling native calls that throw --------- Co-authored-by: Yong He <yonghe@outlook.com>
