    ipa-fnsummary: Include <vector> the proper way
    
    This fixes a bootstrap error with clang 10 that would complain
      /usr/include/c++/v1/typeinfo:346:5: error: no member named
      'fancy_abort' in namespace 'std::__1'; did you mean simply
      'fancy_abort'?
    It mirrors how this is handled in gcov.c and indirectly includes
    <vector> via system.h.
    
    gcc/ChangeLog:
    
            * ipa-fnsummary.c (INCLUDE_VECTOR): Define.
            Remove direct inclusion of <vector>.
