Justin Bogner b86967b006 MIR: Allow parsing of empty machine functions ...

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.
