    libstdc++: Avoid use of naked int32_t in unseq_backend_simd.h, PR108672
    
    The use of a "naked" int32_t (i.e. without a fitting #include:
    stdint.h or cstdint or inttypes.h or an equivalent internal header),
    in libstdc++-v3/include/pstl/unseq_backend_simd.h, caused an error for
    cris-elf and apparently pru-elf and I guess all "newlib targets".
    (Unfortunately, there's a lack of other *-elf targets in recent months
    of gcc-testresults archives.)
    
    This does not manifest on e.g. native x86_64-pc-linux-gnu, because
    there, a definition is included as an effect of including stdlib.h in
    cstdlib (following the trace in native xtreme-header-2_a.ii with
    glibc-2.31-13+deb11u5).  Maybe better than chasing the right #includes
    is to directly use the built-in type, like so:
    
    libstdc++-v3:
    
            PR libstdc++/108672
            * include/pstl/unseq_backend_simd.h (__simd_or): Use __INT32_TYPE__
            instead of int32_t.
