Relanded since the buildbot issue was unrelated to this commit.
When hoisting simple values out from a loop, and an optsize attribute, a
convergent call, or an invoke instruction hindered the pass from
unswitching the loop, the pass would return an incorrect Modified
status.
This was caught using the check introduced by D80916.

This reverts commit dfd447c22043b0a64bf1d146735ca33f926bd22d.
After I pushed this commit, llvm-sphinx-docs started failing, due to:
Warning, treated as error:
extension 'recommonmark' has no setup() function;
is it really a Sphinx extension module?
I don't see how this commit may have caused that, but I'm still
reverting it since I don't know how to proceed with that
troubleshooting.
