OK, I finally figured out the problem. It turns out that "isel" is not (as I had naively assumed) the instruction selection pass, it's a separate pass specific to AMDGPU (confusing name, IMHO).  I changed the test to use "-start-before dwarfehprepare" (a real pass that is not target-specific) and it seems to work now. I will send another patch.
