- add the capability to allocate kernarg buffer in coarse grained GPU memory to leverage caching (off by default)
- implemented a new algorithm to manage kernarg buffers
- provides a control point when to recycle old kernel buffers (for coarse grained buffers)
- more efficient free kernarg buffer lookup
- supports multiple pools with kernarg buffer sizes
