The following patch completes the transition of TREE_CONSTANT_OVERFLOW to
TREE_OVERFLOW by updating the last remaining uses in the Ada front-end.
To summarize the situation, the middle-end has managed to unify the
TREE_OVERFLOW and TREE_CONSTANT_OVERFLOW bits on constant tree nodes, and
now only needs a single bit. To ease the transition, the previously used
TREE_CONSTANT_OVERFLOW is currently a synonym for TREE_OVERFLOW whilst the
various front-ends are transitioned, which is exactly what this patch
does.
The following patch has been tested on i686-pc-linux-gnu, will a full
"make bootstrap", including Ada and regression tested with a top-level
"make -k check" with no new failures. I currently see the same two ACATs
failures and one gnat failure on this platform, as I do in an unpatched
mainline.
Ok for mainline?

* decl.c (gnat_to_gnu_entity): Use TREE_OVERFLOW instead of
TREE_CONSTANT_OVERFLOW.
(allocatable_size_p, annotate_value): Likewise.
* trans.c (gnat_to_gnu): Likewise.
* utils.c (unchecked_convert): Likewise.
* utils2.c (build_simple_component_ref): Likewise.
