[patch] Restore cross-language inlining into Ada

[Eric Botcazou]

Hi,

this patch from Jan:
  https://gcc.gnu.org/ml/gcc-patches/2015-03/msg01388.html
totally disabled cross-language inlining into Ada without notice, by adding a 
check that always fails when the language of the callee is not Ada...
The attached patch simply deletes this new check to restore the initial state.

Tested on x86_64-suse-linux, OK for the mainline?

        * ipa-inline.c (can_inline_edge_p): Back out overzealous check on
        flag_non_call_exceptions compatibility.
