    I've noticed
    +UNRESOLVED: g++.dg/tree-ssa/pr106922.C  -std=gnu++20  scan-tree-dump-not dce3 "m_initialized"
    +UNRESOLVED: g++.dg/tree-ssa/pr106922.C  -std=gnu++2b  scan-tree-dump-not dce3 "m_initialized"
    with this change, both on x86_64 and i686.
    The dump is still cddce3, additionally as the last reference to the pre
    dump is gone, not sure it is worth creating that dump.
    
    With the following patch, there aren't FAILs nor UNRESOLVED tests with
    GXX_TESTSUITE_STDS=98,11,14,17,20,2b make check-g++ RUNTESTFLAGS="--target_board=unix\{-m32,-m64\} dg.exp='pr106922.C'"

            PR tree-optimization/106922
            * g++.dg/tree-ssa/pr106922.C: Scan in cddce3 dump rather than
            dce3.  Remove -fdump-tree-pre-details from dg-options.
    
    (cherry picked from commit a0de11d0d22054b6fd76a0730a3ec807542379d0)
