    perfc: add pseudo-keyword fallthrough
    
    Add pseudo-keyword fallthrough to make explicit the intention of the
    code and meet requirements to deviate MISRA C:2012 Rule 16.3
    ("An unconditional `break' statement shall terminate every
    switch-clause").
    
    No functional change.
