Fix the dump of PipeType.
Now we will have "pipe int" and element type.
Probably it would be forth to add a simple test.
Do you think we could add a test? For example similar to test/Misc/ast-dump-decl.c. We could have it for now in test/SemaOpenCL folder.
I will add a test and send a new version.
Add test and fix some old test.
