Improve tests for valid values of iostream bitmask types 

* testsuite/27_io/ios_base/types/fmtflags/case_label.cc: Explicitly
	check minimum and maximum values, and size of underlying type.
	* testsuite/27_io/ios_base/types/iostate/case_label.cc: Likewise.
	* testsuite/27_io/ios_base/types/openmode/case_label.cc: Likewise.
