    Apply upstream libc++ fix to allow building with devel/xxx-xtoolchain-gcc
    
    Merge commit 52e9d80d5db2 from llvm git (by Jason Liu):
    
      [libc++] add `inline` for __open's definition in ifstream and ofstream
    
      Summary:
    
      When building with gcc on AIX, it seems that gcc does not like the
      `always_inline` without the `inline` keyword.
      So adding the inline keywords in for __open in ifstream and ofstream.
      That will also make it consistent with __open in basic_filebuf
      (it seems we added `inline` there before for gcc build as well).
