LibJS: Make ASTNode::generate_bytecode() fallible Instead of crashing on the spot, return a descriptive error that will eventually continue its days as a javascript "InternalError" exception. This should make random crashes with BC less likely. 2022-02-12 19:54:08 +03:30			`/*`

Everywhere: Rename to_{string => deprecated_string}() where applicable This will make it easier to support both string types at the same time while we convert code, and tracking down remaining uses. One big exception is Value::to_string() in LibJS, where the name is dictated by the ToString AO. 2022-12-06 01:12:49 +00:00			`DeprecatedString to_deprecated_string();`
