    Apply SplitSections to all C compilations
    
    Previously this was added only to the RTS's C files (those are the bulk
    of it though), but there are C bits in ghc-prim, integer-gmp and base
    too.
    
    Followup for #8405, allows the large table of character properties in
    base to be stripped when not used.
    
    Test Plan: validate
