configs, cpu: fix crashes related to switch_cpus
The decoder objects are turned into SimObjects. However,
the decoder objects vector is initialized by calling
`createThreads`(defined in BaseCPU.py). However, there is
no code calling `createThreads` for switch_cpus.
As a result, all functions related to it are broken
(e.g. fast-forward, checkpoint).
