    Summary:
    folly/Range.h is extensively used in fbcode, try to avoid including
    <iostream> (which is pretty heavy), include forward declarations
    (<iosfwd>) instead.
    
    Also transitioned it from 'std type_traits' + 'boost type_traits' to
    'std type_traits'.
    
    Test Plan: compiled, ran tests
