Summary: Compiling CUDA device code requires us to know the host toolchain, because CUDA device-side compiles pull in e.g. host headers. When we only supported Linux compilation, this worked because CudaToolChain, which is responsible for device-side CUDA compilation, inherited from the Linux toolchain. But in order to support MacOS, CudaToolChain needs to take a HostToolChain pointer. Because a CUDA toolchain now requires a host TC, we no longer will create a CUDA toolchain from Driver::getToolChain -- you have to go through CreateOffloadingDeviceToolChains. I am *pretty* sure this is correct, and that previously any attempt to create a CUDA toolchain through getToolChain() would eventually have resulted in us throwing "error: unsupported use of NVPTX for host compilation". In any case hacking getToolChain to create a CUDA+host toolchain would be wrong, because a Driver can be reused for multiple compilations, potentially with different host TCs, and getToolChain will cache the result, causing us to potentially use a stale host TC. So that's the main change in this patch. In addition, we have to pull CudaInstallationDetector out of Generic_GCC and into a top-level class. It's now used by the Generic_GCC and MachO toolchains.
