* tree.h (TYPE_STRING_FLAG): Document that this field may be used

signed_char_type_node, unsigned_char_type_node and char_type_node.
* dwarf2out.c (base_type_die): Treat CHAR_TYPE identically to
INTEGER_TYPE. Use TYPE_STRING_FLAG to decide whether to emit
a DW_ATE_[un]signed_char instead of a DW_ATE_[un]signed.
