Support --incremental with --module AMD

Suggestion

Support using the --incremental flag when outputting AMD modules.

Use Cases

Projects that use the AMD module format should be able to get the performance benefits that come with --incremental. Currently testing locally it appears that using --incremental makes a large difference for compilation speed when outputting to ES6 modules but didn't make any difference for AMD.

Examples

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

Inizia tracciando come viene gestita l’opzione --incremental per l’output dei moduli ES6 e AMD, quindi individua lo stato del compilatore o i percorsi di emit che differiscono tra loro. Confronta il comportamento incrementale esistente e i test rilevanti del compilatore, e definisci come completato il fatto che la compilazione AMD ottenga lo stesso supporto alle prestazioni incrementali senza modificare il comportamento del runtime emesso.
