[PATCH] Fixup canonicalize_constructor_val some more

[Richard Guenther]

Make sure to mark decl addresses coming from constructors
as addressable (otherwise early folding fails for all java testcases).

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

Richard.

        * gimple-fold.c (canonicalize_constructor_val): Mark
        address-taken variables addressable.
