  Log Message:
  -----------
  Add an instruction marker field to the ExtraInfo in MachineInstrs.

Summary:
Add instruction marker to MachineInstr ExtraInfo. This does almost the
same thing as Pre/PostInstrSymbols, except that it doesn't create a label until
printing instructions. This allows for labels to be put around instructions that
are deleted/duplicated somewhere.

Also undo the workaround in r375137.
