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.
