Little step toward heterogeneous emulation. After few trivial
cleanups, allow accel_cpu_common_realize() -> tcg_exec_realizefn()
to call frontend TCGCPUOps::initialize() for different targets.

Philippe Mathieu-Daudé (6):
  target/ppc: Indent ppc_tcg_ops[] with 4 spaces
  accel/tcg: Declare local tcg_ops variable in tcg_exec_realizefn()
  accel/tcg: Rename TCGCPUOps::initialize() as initialize_once()
  include: Expose QemuArch in 'qemu/arch_id.h'
  accel/tcg: Add TCGCPUOps::arch_id field
  accel/tcg: Allow tcg_exec_realizefn() initialize multiple frontends
