avoid generation of empty guards in trivial cases
We used to insert a trivial integer_onep condition around loops we know have
more than an iteration. This patch avoids generating those conditions.
* graphite-isl-ast-to-gimple.c (graphite_create_new_loop_guard): Do not call
create_empty_if_region_on_edge when cond_expr is true.
(translate_isl_ast_node_for): Check whether a guard has been generated.
