[PATCH] PR fortran/95709 - [9/10/11 Regression] ICE in gfc_resolve_code, at fortran/resolve.c:11807

I've played around some more with invalid uses of assigned GOTO and found
that some cases produced a suboptimal error message.  The attached patch
(v2) improves upon this and provides a slightly larger testcase.

Again regtested on x86_64-pc-linux-gnu.

OK for master / backports?

Thanks,
Harald
