Flatten anonymous structs in CodeView types

If a CodeView struct, class, or union has as a member an anonymous
struct, class, or union, this gets flattened. The sub-struct's members
will appear as if they were part of their parent.

For this, we move part of get_type_num_struct into a new function
add_to_fieldlist, which also handles creating an LF_INDEX overflow item
if an LF_FIELDLIST grows too large. This is because add_struct_member
now calls itself recursively, and so needs to handle overflows itself.

gcc/
	* dwarf2codeview.cc (add_to_fieldlist): New function.
	(add_struct_member): Call recursively to flatten structs, and call
	add_to_fieldlist.
	(add_struct_static_member): Call add_to_fieldlist.
	(add_struct_function): Call add_to_fieldlist.
	(add_struct_inheritance): Call add_to_fieldlist.
	(add_struct_nested_type): Call add_to_fieldlist.
	(get_type_num_struct): Move code to add_to_fieldlist, and move
	responsibility for this to subfunctions.
