Cut the hyperbole please, this change does not affect "every other project out there". This change makes clang match GCC's 15+-year behaviour that other projects out there will have come to expect. I find it baffling that Chrome/Chromium developers would rely on a bug, knowing full well it's a bug judging from their own comments, and then not take responsibility for the breakage when that bug is fixed. However, I'll defer to @rsmith on whether this is sufficient reason for reverting, I do not feel qualified to make that judgement.

The MSVC compatibility, however, is something I hadn't foreseen and had just submitted a fix for, D95392 <https://reviews.llvm.org/D95392>. If this change is to be reverted, I'll withdraw that followup fix for now.
