[Qemu-ppc] [PATCH 1/5] exec: [tcg] Track which vCPU is performing translation and execution |

Information is tracked inside the TCGContext structure, and later used
by tracing events with the 'tcg' and 'vcpu' properties.
The 'cpu' field is used to check tracing of translation-time
events ("*_trans"). The 'tcg_env' field is used to pass it to
execution-time events ("*_exec").
