* gdbtypes.h: Add TYPE_FLAG_TARGET_STUB.

Browse source 
* gdbtypes.c (check_stub_type): On TYPE_FLAG_TARGET_STUB, do
	what cleanup_undefined_types does for arrays, except we clear
	TYPE_FLAG_TARGET_STUB if we fix up the type.
	* stabsread.c (cleanup_undefined_types): Add comments about how
	doing arrays here is no longer the clean way to do it.
	(read_array_type): Set TYPE_FLAG_TARGET_STUB as well as calling
	add_undefined_type.
	* c-typeprint.c, ch-typeprint.c: Move call to check_stub_type
	outside switch so it happens for all type codes.
	* cp-valprint.c (cp_print_value_fields): Recurse to val_print,
	instead of c_val_print, so that check_stub_type gets called.

	* gdbtypes.h, gdbtypes.c, m2-lang.c, ch-lang.c, c-lang.c: Remove
	TYPE_FLAG_SIGNED.  It was inconsistently set, never checked
	(except in recursive_dump_type), and is pointless.
