r600: enable ARB_transform_feedback_overflow_query

Browse source 
This functionality was mostly implemented but not enabled.
The functionality which is using SET_PREDICATION seems to
not work as expected.

This change was tested on palm, barts and cayman,
piglit tests (26/28), and khr-gl45 tests (7/13).
