ada-tree.def (LOOP_STMT): Change to 4-operand nodes.
* gcc-interface/ada-tree.def (LOOP_STMT): Change to 4-operand nodes.
* gcc-interface/ada-tree.h (LOOP_STMT_TOP_COND, LOOP_STMT_BOT_COND):
Merge into...
(LOOP_STMT_COND): ...this.
(LOOP_STMT_BOTTOM_COND_P): New flag.
(LOOP_STMT_TOP_UPDATE_P): Likewise.
* gcc-interface/trans.c (can_equal_min_or_max_val_p): New function.
(can_equal_min_val_p): New static inline function.
(can_equal_max_val_p): Likewise.
(Loop_Statement_to_gnu): Use build4 in lieu of build5 and adjust to
new LOOP_STMT semantics. Use two different strategies depending on
whether optimization is enabled to translate the loop.
(gnat_gimplify_stmt) <LOOP_STMT>: Adjust to new LOOP_STMT semantics.
