<pre>Noticed this when I tried committing r342233. A build bot failed
(<a href="http://lab.llvm.org:8011/builders/clang-with-thin-lto-ubuntu/builds/12667">http://lab.llvm.org:8011/builders/clang-with-thin-lto-ubuntu/builds/12667</a>)
when running lld's "ELF/lto/cache.ll". I reverted the change, although looking
at the code, I can't see any way my change could have interacted with it. The
buildbot went green.
However, I then noticed that a practically identical test failed in the same
manner a bit later, some time after my revert landed. See
<a href="http://lab.llvm.org:8011/builders/clang-with-lto-ubuntu/builds/10313">http://lab.llvm.org:8011/builders/clang-with-lto-ubuntu/builds/10313</a>, where
"tools/gold/X86/cache.ll" failed. The test passed on the next run of the
buildbot, with no related changes.
And just now the LLD test failed again:
<a href="http://lab.llvm.org:8011/builders/clang-with-lto-ubuntu/builds/10315">http://lab.llvm.org:8011/builders/clang-with-lto-ubuntu/builds/10315</a>.
I'm guessing the root cause of these test failures is the same.</pre>
