[COMMITTED] ada: Don't pretty-print DEL within expression images

[Marc Poulhiès via Gcc-patches]

From: Piotr Trojanek <troja...@adacore.com>

When printing expression images, e.g. for GNATprove counterexamples,
it seems better to print DEL not directly but with its numeric code.

gcc/ada/

        * pprint.adb (Expr_Name): Exclude DEL from printable range.

Tested on x86_64-pc-linux-gnu, committed on master.
