I really don't think this is the right way to go because the dumps
change if we suddenly use an extra temporary during gimplification,
or delete a PHI and recycle an SSA_NAME that wasn't recycled before,
or due to addresses of temporary variables changing, etc etc.

Instead I would ask that you look into how to expand the testing
infrastructure to allow you do write tests more reasonably without
just diffing the dump files.
