* trans-stmt.h: Add prototype for gfc_trans_code_cond. Add tree cond to
gfc_trans_do prototype.
* trans-stmt.c (gfc_trans_simple_do): Add optional argument to pass in
a loop exit condition. If exit condition is given, build the loop exit
code, checking IO results of implied do loops in READ and WRITE.
(gfc_trans_do): Likewise.
* trans.c (trans_code): New static work function, previously
gfc_trans_code. Passes exit condition to gfc_trans_do.
(gfc_trans_code): Calls trans_code with NULL_TREE condition.
(gfc_trans_code_cond): Calls trans_code with loop exit condition.
* trans-io.c (build_dt): Build an exit condition to allow checking IO
result status bits in the dtparm structure. Use this condition in call
to gfc_trans_code_cond.
