Detailed Description

Split all kernels in a module into sub-kernels. The sub-kernels should be called as functions from the main kernel. The assumption is that all threads will execute a sub-kernel, hit a barrier, and enter the next sub-kernel.

This pass may optionally insert an explicit scheduler kernel that is responsible for doing fine-grained scheduling of the next function to execute and control transition between functions. This is necessary to support intelligent scheduling on architectures without runtime support (mainly GPUs).
