Revert "i965/compaction: Disable compaction on SNB temporarily."

This reverts commit cabc93c5adc9ea62be901621eff5ce4cb9574791.

Mark thinks the failures on the SNB GT2 in the lab are actually because
of faulty hardware, not instruction compaction. The GT1 didn't see any
problems after changes to the compaction code.
