I usually want to run -print-after-all, split the output into files, and diff files corresponding to consecutive passes. If the entire module _is_ dumped, the diff is less clean. Hence just the func IR.

With the suggested change, the function will get dumped in _addition_ to the module when -print-module-scope is specified, I think. Since the function is a part of the module, this seems redundant.
