Fix tests that fail when compiled without optimisation

	* testsuite/20_util/duration/literals/range_neg.cc: Adjust pruned
	diagnostic to account for quotes around 'constexpr'.
	* testsuite/23_containers/deque/capacity/max_size.cc: Define static
	variable.
	* testsuite/23_containers/vector/capacity/max_size.cc: Likewise.
