  Log Message:
  -----------
  [MCA] Refactor the InOrderIssueStage stage. NFCI

Moved the logic that checks for RAW hazards from the InOrderIssueStage to the
RegisterFile.

Changed how the InOrderIssueStage keeps track of backend stalls. Stall events
are now generated from method notifyStallEvent().

No functional change intended.
