[PATCH] D39044: [MachineRegisterInfo] Avoid having dbg.values affect code generation

[Mikael Holmén via Phabricator via llvm-commits]

Not sure who should review this. Added Matthias who seems to have reviewed other patches in MRI.

Does this make sense even without a test case?

When I've tried to reproduce on X86 there always seems to be another COPY making use_empty() return
false, or the dbg.value has been dropped for some reason during ISel.
