c++: ICE on invalid with NSDMI in C++98 [PR98352]

NSDMIs are a C++11 thing, and here we ICE with them on the non-C++11
path.  Fortunately all we need is a small tweak to my recent r11-7835
patch.

gcc/cp/ChangeLog:

	PR c++/98352
	* method.c (implicitly_declare_fn): Pass &raises to
	synthesized_method_walk.

gcc/testsuite/ChangeLog:

	PR c++/98352
	* g++.dg/cpp0x/inh-ctor37.C: Remove dg-error.
	* g++.dg/cpp0x/nsdmi17.C: New test.
