Subject: IAR doesn't support __attribute__((fallthrough))

IAR generates warning Pa167 'the "fallthrough" attribute is not supported'.
It doesn't generate warnings when one switch case falls through to another,
so simply make TU_ATTR_FALLTHROUGH expand to an empty string.

Also replace one instance of __attribute__ with the macro.
