Original commit message:

    [debugger] Fix code coverage for break/return inside switch-case

    Case statements have a list of statements associated with them, but are
    not blocks, and were hence not fixed-up correctly for code coverage.
    This CL also applies the fix-up to the "body" of case statements,
    in this way removing ranges reported as uncovered between the final
    break/return in a case and the next case (or end of function).

    Drive-by: Add optional pretty printing to code coverage test results.
