To test a change to GVN it would be best to have a .ll file with a RUN: line that invokes opt (with the appropriate flags for GVN) and then CHECKs the output with FileCheck. You can grep for "RUN: opt” in test/ for some examples.
Assuming that you have source code for a testcase, you can extract an appropriate fragment from the output go -mllvm -print-after-all.
