middle-end/103851 - ensure SSA names are released during OMP lowering
This makes sure to release moved & remapped SSA names during OMP
outlining which happens before going into SSA but with SSA names
created by gimplification around.

PR middle-end/103851
* tree-cfg.c (move_sese_region_to_fn): Always release SSA names.
* g++.dg/gomp/pr103851.C: New testcase.
