If you run llc -stop-after=codegenprepare and feed the resulting MIR to llc -start-after=codegenprepare, you'll have an empty machine function since we haven't run any isel yet. Of course, this only works if the MIRParser believes you that this is okay. This is essentially a revert of r241862 with a fix for the problem it was papering over. llvm-svn: 299975
