[babel] Add panicOnBailout option

Adds an option to always throw errors regardless of severity (default, ie the 
status quo), or when the flag is disabled, only critical errors will be thrown. 
Any error that isn't considered a critical error (see 
`CompilerError.isCritical()`) since it might indicate that the compiler is 
buggy, while non-critical errors will result in that file being skipped for 
compilation, but otherwise continue compiling other files
