Function miri::create_ecx

pub fn create_ecx<'mir, 'tcx: 'mir>(
    tcx: TyCtxt<'tcx>,
    entry_id: DefId,
    entry_type: EntryFnType,
    config: &MiriConfig
) -> InterpResult<'tcx, (InterpCx<'mir, 'tcx, Evaluator<'mir, 'tcx>>, MPlaceTy<'tcx, Provenance>)>

Returns a freshly created InterpCx, along with an MPlaceTy representing the location where the return value of the start function will be written to. Public because this is also used by priroda.
