Philippe Mathieu-Daudé 482869ca84 accel/tcg: Name gen_goto_tb()'s TB slot index as @tb_slot_idx 
tcg_gen_goto_tb() takes an unsigned index to the TB slot (0 or 1).
Declare the argument as unsigned and rename it as @tb_slot_idx
(which is more descriptive than @n) on all targets.

Richard Henderson 4759aae432 accel/tcg: Return TCGTBCPUState from cpu_get_tb_cpu_state 
Combine 3 different pointer returns into one structure return.

Include a cflags field in TCGTBCPUState, not filled in by
cpu_get_tb_cpu_state, but used by all callers.  This fills
a hole in the structure and is useful in some subroutines.
