[PATCH] [OPENMP] Codegen for 'firstprivate' clause in 'single' directive.

[Alexey Bataev]

Hi rjmccall, hfinkel,

Emit the following code for 'single' directive with 'firtstprivate' clause:
```
if (@__kmpc_single()) {
<init for firstprivates>
@__kmpc_end_single();
}
@__kmpc_cancel_barrier(); // To avoid data race in firstprivate init

```
