Patch to dwarf2out.c:scope_die_for

[Jason Merrill]

This broke if we got called to emit the info for a nested type while in a
member function; the logical scope of the function doesn't match the actual
DIE nesting, so we failed.  In that situation, the right thing to do is to
stick the nested type at file scope, so just do it.  Applied.

	* dwarf2out.c (scope_die_for): Set scope_die to comp_unit_die
	rather than asserting it.
