Kevin,
I don't know if this changes anything, but there is some support for checking MachineIR via the -stop-after and -start-before options to llc. I used it in the /test/CodeGen/X86/machine-combiner-int.ll regression test to verify that machine operands are dead. There are probably better examples in other regression tests.
