CPU models (and especially some additional details which we will start probing for later) differ depending on the accelerator. Thus we need to call query-cpu-definitions in both KVM and TCG mode to get all data we want. Tests in tests/domaincapstest.c are temporarily switched to TCG to avoid having to squash even more stuff into this single patch. They will all be switched back later in separate commits.
