Implemented codegen for the iterator expression in the depend clauses.
Iterator construct is emitted the following way:
iterator(cnt1, cnt2, ...), in : <dep>
<TotalNumDeps> = <cnt1_size> * <cnt2_size> * ...;
kmp_depend_t deps[<TotalNumDeps>];
deps_counter = 0;
for (cnt1) {
for (cnt2) {
...
deps[deps_counter].base_addr = &<dep>;
deps[deps_counter].size = sizeof(<dep>);
deps[deps_counter].flags = in;
deps_counter += 1;
...
}
}
For depobj construct the codegen is very similar, but the memory is
allocated dynamically and added extra first item reserved for internal use.
