[Regression] PPU loading never finishes for some titles (#13534)

Quick summary

Starting with PR 13534, the loading screens for PPU caches on some games never complete when they should.

Details

Starting with PR 13534, the loading screens for PPU caches on some games never complete when they should, sitting on "Linking PPU Modules" indefinitely, but without anything crashing. Manually closing will cause a deadlock. Watch Dogs is a perfect example and what I used for my logs.

Apparently if you wait a veeeeery long time, it makes it ingame... only to be met with issue #13723.

Seems related to #13877

[Darkhost1999]

Yes, this is the same issue reported before the other 1 was posted. Yet the other 1 is more informative that this issue is more widespread than 1 game.
Watchdogs may be one of the most afflicted.

Worth retesting with #14090

[SlyCooperReloadCoded]

Nope, still an issue as of latest master.

[SlyCooperReloadCoded]

This still happens for me on latest master, and on every game in my library, Watch Dogs taking the longest. Just hangs there at "Linking PPU modules" for up to 10 minutes with nothing printing to the log, just like before.

I believe LLVM 17 will be here in October. Not just a release candidate but hopefully an actual release. Maybe it'll get resolved with us bumping LLVM when the time comes.

Could also be a good idea to update to 16.0.5 in the meantime, since we're using 16.0.1
