<pre>The EarlyCSE case has been implemented for some time, even without MemorySSA.
It looks like the wrong GVN test case was mistakenly attached (since it has no
occurrences of invariant.load), but this optimization has also been implemented
in GVN (see llvm/test/Transforms/GVN/PRE/invariant-load.ll).</pre>
