Tobias Bosch 745b59f49c perf(compiler): only emit changed files for incremental compilation
For now, we always create all generated files, but diff them
before we pass them to TypeScript.

For the user files, we compare the programs and only emit changed
TypeScript files.

This also adds more diagnostic messages if the `—diagnostics` flag
is passed to the command line.
