This is part of the original PR #5544 that takes care of the daemon performance regression caused by #5465. (I separated it from original PR as requested by @JukkaL.)
I will add tests I promised in #5544 (daemon variants of the tests added in #5465 and #5544).
This change should not affect semantics, only performance by avoiding cloning options for lots of modules in situation with
--follow-imports=skip
.
