They are not necessarily meaningless, they may partition code into some logical parts, and highlight those parts and comments applying to those whole parts visually.

It doesn't necessarily have to be /////////////////////// (which are unintentionally treated as doc comments), just something big and visible "from the distance".

They're not treated as doc comments are they? Some of the ones I left in were trying to illustrate it such as the ones in src/test/ui/issues/issue-10638.rs.
The majority of the deleted ones were the only comments in the file, so most people's syntax highlighting will make them stand out. They also differ from the doc comments, so they stand out that way. Some of them use capitalisation to stand out, and looking through as I removed them none of them seemed to have their value diminished by the lack of separators.
I guess the discussion is more whether the issue should be there in the first place, but no one has suggested otherwise on it.

Further to this, if code within a file is in so many distinct parts that it needs partitioning, perhaps it shouldn't be in the same module?

Hmm, I'm not really sure what's causing the errors here. The only diff from master for the file with problems is comment removal.

Overall I'm conflicted about removing some of these section comments; they seem useful and I use them myself from time to time (with // =====). In other words, I basically agree with @petrochenkov. That said, perhaps the better thing to do here is to look for opportunities to split modules. I would look for the largest sections which fit as a coherent unit and split those out.

This is also good; comment is useless.

Further to this, if code within a file is in so many distinct parts that it needs partitioning, perhaps it shouldn't be in the same module?

No, not at all, the sections may be small and contain just several logically related methods.
This is really a matter of personal taste.

Please, keep the highlighting in librustc_privacy/lib.rs (in some form) and don't split it into modules, otherwise I don't care much.

Personally I think it largely depends on size; if a section is > 500 LOC and makes sense as a logical unit then a module is probably a good thing.

I've put back the ones in librustc_privacy/lib.rs. I agree they make it more readable but feel that's probably because something needs splitting out given that it's almost 2000 LOC total. Alas, I'm not quite sure what that would be.
