[PATCH] Add debug_bb_details and debug_bb_n_details

[Xiong Hu Luo via Gcc-patches]

Sometimes debug_bb_slim&debug_bb_n_slim is not enough, how about adding
this debug_bb_details&debug_bb_n_details? Or any other similar call
existed?

gcc/ChangeLog:

2020-10-23  Xionghu Luo  <luo...@linux.ibm.com>

        * print-rtl.c (debug_bb_details): New function.
        * (debug_bb_n_details): New function.
