[BOLT] Option to fail if invalid profile detected

Summary:
Add an option to fail processing of the input binary if the profile
is not accurate:

  -stale-threshold=<uint>
    - maximum percentage of stale functions to tolerate (default: 100)

Default (100) means never to fail.

A function profile is considered stale if any branch in its profile
has invalid source or destination.

Use `-stale-threshold=0` to fail if any staleness is detected in the
profile.
