The attached patch enables it for the C family of languages (I'm not too sure

The flag isn't formally tied to -fnon-call-exceptions though, so there might be
subtleties in C++

Here is what I've installed after bootstrapping/regtesting on x86_64-suse-linux
and i586-suse-linux. It adds the flag to 'struct function' and stre

If we don't do it, we'll get another PR saying "this works in LTO mode with
other versions of the Ada compiler" (which is true) so I'll proceed.

This PR is about straight-line code not being as much vectorized in Ada as in C
or C++. The problem stems from the very conservative semantics implemented
under -fnon-call-exceptions for the sake of Java. We don't need it in Ada.
Tested on x86_64-suse-linux, OK for the mainline?
