Hi.The patch reverts mangling of filenames due to file length limitation. Creation of a folder tree seems fine in context of PGO. Ready for master?

But what was motivation for introducing them at first place?
The motivation is described here: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91971#c0 Well, the original issue is not a fundamental problem. I'm going to install the patch. Martin
Patch is OK unless that reason was very good :) Honza
