[commit/Ada] Attach ada_executable_changed_observer

[Joel Brobecker <brobecker at adacore dot com>]

Ooops!

In a change I made a few months ago, I defined a function that was
meant to be attached as an observer of the executable-changed
notification, but never actually attached it. Not sure if I forgot,
or that piece was missing from the patch.  The part that I don't
understand is why I didn't get a warning from the compiler, since
the function is static but unused.

The symptoms would only appear if a user debugged a program using
the old runtime (in terms of exception support), and then debugged
a program with the new one (or vice versa) without restarting the
debugger. Exception catchpoints would not work properly in the second
case. That's pretty minor, but easily fixeable.

        * ada-lang.c (_initialize_ada_language): Attach executable_changed
        observer.

Tested on x86-linux. No regression.
