Initial check-in of Acxxel (StreamExecutor renamed) Summary: Acxxel is basically a simplified redesign of StreamExecutor. Here are the major points where Acxxel differs from the current StreamExecutor design: * Acxxel doesn't support the kernel and kernel loader types designed for emission by the compiler to support type-safe kernel launches. For CUDA, kernels in Acxxel can be seamlessly launched using the standard CUDA triple-chevron kernel launch syntax that is available with clang and nvcc. For CUDA and OpenCL, kernel arguments can be passed in the old-fashioned way, as one array of pointers to arguments and another array of argument sizes. Although OpenCL doesn't get a type-safe kernel launch method, it does still get the benefit of all the memory management wrappers. In the future, clang may add support for triple-chevron OpenCL kernel launchs, or some other type-safe OpenCL kernel launch method. * Acxxel does not depend on any other code in LLVM, so it builds completely independently from LLVM. The goal will be to check in Acxxel and remove StreamExecutor, or perhaps to remove the old StreamExecutor and rename Acxxel to StreamExecutor, so I think Acxxel should be thought of as a new version of StreamExecutor, not as a separate project.

[Acxxel] Remove setActiveDeviceForThread Summary: After experimenting with CUDA, I realized that we really only need to set the active context right before creating an object such as a stream or a device memory allocation. When we go on to use these objects later, it is fine if the context that created them is no longer active, operations with those objects will succeed anyway. Since it turns out that we don't have to check the active context for every operation, it makes sense to hide this active context from users (by removing the "ActiveDeviceForThread" setter and getter) and to change the Acxxel API to explicitly pass in the device ID to create objects. This change improves the Acxxel API and greatly simplifies the CUDA and OpenCL implementations because they no longer require thread_local data.
