Cannot find similar chunks because of filename with hash

[erykpiast]

Load these two stat files to see the issue:

Archive.zip

The resulting filename of chunks contains content hash (which is, the pretty common configuration) and because of that, chunks cannot be compared between builds. names collection is empty, so files is used as a fallback which is not the best idea in this case.

The best idea that comes to my mind now is to extend the comparison algorithm, so it's like this:

• check the names collection
• when there is no match, check files collection
• when there is no match, check the identifier of the entry points (the first one? all? any?)
• when there is no match, rely on the order

There is a risk for a false-positive match, though, especially when chunks are added/removed/reordered. react-dev-utils does it by simply removing anything that looks like hash from the filename. Simple, but works in most cases, maybe that's the way?
