If this, then I guess this together with the following SET_DECL_RTL NULL
should be put into a new make_decl_rtl_for_debug helper (or something
similar), with a big comment why it is doing that.
Dropping of alias sets from -fdump-final-insns is risky, we'd miss if
DEBUG insns/stmts actually cause any real aliasing changes.
