Let's test this through SPIR-V first. I've only tested direct OpenCL C calls. |

With the device side abort extension, a work-item (WI) can return from the kernel execution at any point and cause abnormal unrecoverable termination of the host process.
This extension differs from the cl_arm_controlled_kernel_termination extension in that the abort in the device side is expected to behave like a call to the POSIX abort() in the host side, terminating also the host process immediately.
The extension is meant to easily support POSIX abort()-like functionality on the device side, as well as serve as a basis for CUDA/HIP-style assertions.
