I have measured the number of decls created before/after the patch
(well, some earlier patch ...) by means of dumping next_decl_uid
after compile_file (). The number is reduced, that's all I can say.
The main motivation of the patch was to simplify SSA pass coding,
not so much saving memory (for that you'd need to avoid creating the
decls during gimplification in the first place).
