Separate updateComments from updateExpectations.

Separate updateComments from updateExpectations.

Previous to this CL, the updateExpectations flag had two effects:

- It caused ".expect" files to be updated.

- It caused embedded expectations comments in ".dart" files (of the
  form "/*@key=value*/") to be updated.

I'm finding that I frequently want to update the former but not the
latter, so I'm splitting this into two separate flags.

With this CL, updateExpectations only updates ".expect" files, and
updateComments only updates embedded expectations comments.
