This patch just adds a test case to show the differences in code emitted
by opt before and after https://reviews.llvm.org/D61726.
Previous attempt to commit this did not include the registered target
requirement so it caused buildbot breaks.
llvm-svn: 360620
The test case checks were produced by the update_test_checks.py
scripts and I assumed that is sufficient. However, the behaviour
is different with different default target triples. Specify the
triple explicitly in the test case.
If this doesn't clean up the build bot breaks, I'll remove the test
case until I can get to the bottom of why the behaviour on build bots
is different from my machine.
