Initial implementation of whole module optimization mode, which processes all of the input files for a target in a single invocation, and there is no notion of a "primary file".
…jobs. Eliminates a DRY violation in `emitModuleJob` / `mergeModuleJob` involving the paths for a number of module-level outputs. Call into a common method `addCommonModuleOptions` instead of duplicating the logic.
… builds. For outputs that can only be created when processing the module as a whole, add them to the compile job for a single-file compile.
This is useful for writing a test, but needs to be generalized.
When we’re performing a single frontend job for the entire module, query the output file map for that single entry.
`OutputFileMap` is effectively growing a copy of `FileType` in it, which is unfortunate. Add yet one more entry (for serialized diagnostics files), but because this isn’t a robust solution, add a TODO to the README to generalize the implementation.
