This patch seems to have had catastrophic results on the build times in the `libc` project. See the buildbot where the build times have gone from ~15 minutes to over an hour https://lab.llvm.org/staging/#/builders/247. Reverting this patch causes the time for my to build a test to go from 55 seconds to 5 seconds. I can try to get pass timing later.
