[Ada] Unnesting: allow uplevel references to exceptions
2018-05-28 Ed Schonberg <schonberg@adacore.com>
gcc/ada/
* einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
they can appear as components of activation records.
* exp_unst.adb (Visit_Node): A reference to an exception may be an
uplevel reference.
