  Log Message:
  -----------
  [SampleFDO] Report error when reading a bad/incompatible profile instead of
turning off SampleFDO silently.

Currently sample loader pass turns off SampleFDO optimization silently when
it sees error in reading the profile. This behavior will defeat the tests
which could have caught those bad/incompatible profile problems. This patch
change the behavior to report error.
