Tom Tromey 37f6a7f456 Add $_ada_exception convenience variable
This adds the $_ada_exception convenience variable.  It is set by the
Ada exception catchpoints, and holds the address of the exception
currently being thrown.  This is useful because it allows more
fine-grained filtering of exceptions than is possible using the
existing "catch" syntax.

This also simplifies Ada catchpoints somewhat; because the catchpoint
must now carry the "kind", it's possible to remove many helper
functions.
