Currently we report whether the TCG accelerator is in 'one-insn-per-tb' mode in the 'info status' output. This is a pretty minor piece of TCG specific information, and we want to deprecate the 'singlestep' field of the associated QMP command. Move the 'one-insn-per-tb' reporting to 'info jit'. We don't need a deprecate-and-drop period for this because the HMP interface has no stability guarantees.
