Suddenly idea began consuming the cpu aggressively.
Typical value is 15% (single core, hyper-threading enabled cpu) when absolutely idle and no files open.
50% when trying to type in a file.

How many unversioned files do you have?

I have 5700 unversioned files.
I guess I should add their directories to ignored list

It's even better to set the version control to None for these directories, using Settings | Version Control | Directory Version Control Settings.

Unfortunately some of these directories are buried deep under the project root. Adding all but these directories would be a tricky job.
Maybe I should try to redesign directory structure if it helps much.

Can't IDEA improve its performance in this area? It is not good that people are starting to have to seriously consider redesigning directory structures because of IDEA peformance.

It can, and it will. I'm not closing this issue - I'm just talking about workarounds which can be used in the current version.

Could you, please, explain what does this fix mean.
Does it mean I mustn't bother adding directories with lots of unversioned files to ignored list? Or, maybe, ignore list handling was made as fast as if you just don't add these dirs under source control?

I've optimized the specific operation that took a long time in your snapshot. Now its speed does not depend on the number of unversioned files. However, there are still other operations that are slowed down by a large number of unversioned files. So it still does make sense to set VCS to None for directories with generated code and similar types of content.
