Pretty much straightforward change which gives around 30% speedup on my laptop and around 2x speedup on desktop in the BI (which uses gts580). Tested with huge blurs (like 10% of blur) which was rather common during Caminandes. For now OpenCL is only limited for blur size more than 100 pixels. This is a bit experimental still, feedback is welcome. Reviewers: jbakker, lukastoenne Subscribers: ton Differential Revision: https://developer.blender.org/D576
