c: Fix compile time hog in c_genericize [PR107127]
The complex multiplications result in deeply nested set of many SAVE_EXPRs,
which takes even on fast machines over 5 minutes to walk.
This patch fixes that by using walk_tree_without_duplicates where it is
instant.

* c-gimplify.cc (c_genericize): Use walk_tree_without_duplicates
instead of walk_tree for c_genericize_control_r.
