[llvm] r301885 - Revert r301880

[George Burgess IV via llvm-commits]

yeah, here's the first failure i have with a helpful stack trace:
http://lab.llvm.org:8011/builders/clang-x86_64-linux-
selfhost-modules-2/builds/6968/steps/compile.llvm.stage2/logs/stdio (grep
for "#0 0x0000000001c662fd")

the simplest way I found to repro it on my machine is `ninja
check-sanitizer` on a release build; clang should ICE on a file or two.
