Added codegen for taskgroup directive with task_reduction clause.
```
<body>
```
The next code is emitted:
```
%struct.kmp_task_red_input_t red_init[n];
void *td;
call void @__kmpc_taskgroup(%ident_t id, i32 gtid)
...
red_init[i].shar = &<item>;
red_init[i].size = sizeof(<item>);
red_init[i].init = (void*)initializer_function;
red_init[i].fini = (void*)destructor_function;
red_init[i].comb = (void*)combiner_function;
red_init[i].flags = flags;
...
td = call i8* @__kmpc_task_reduction_init(i32 gtid, i32 n, i8*
(void*)red_init);
call void @__kmpc_end_taskgroup(%ident_t id, i32 gtid)
void initializer_function(i8* priv) {
*(<type>*)priv = <red_init>;
ret void;
}
void destructor_function(i8* priv) {
(<type>*)priv->~();
ret void;
}
void combiner_function(i8* inout, i8* in) {
*(<type>*)inout = *(<type>*)inout <red_id> *(<type>*)in;
ret void;
}
