cppfiles.c (redundant_include_p): Provide length of token to cpp_defined.

	* cppfiles.c (redundant_include_p): Provide length of token to
	cpp_defined.
	* cpphash.c (_cpp_make_hashnode, _cpp_lookup_slot): Hash
	values are unsigned int.
	(_cpp_lookup, _cpp_lookup_slot): Do not calculate the length.
	(_cpp_lookup_slot): Do not calculate the hash, either.
	* cpphash.h: Update prototypes.
	* cpplib.c (do_define, do_undef, do_pragma_poison, do_assert):
	Hashes are unsigned int.  Calculate hash here, pass by value
	to _cpp_lookup_slot.
