The existing workgroup calculation logic for GWS initialization is incorrect. It tries to add together workgroups across dimensions, leading to major under-count in 2D and 3D kernels. An (x,y,z) kernel uses x * y * z blocks, not x + y + z. In addition, the previous logic was incorrect for the case of launching a single-threaded kernel. It calculated 0 workgroups, leading to initializing GWS to -1. Change-Id: I1bb20a0d5b6e0cc10ac55901c28d8f93aac61c09
