rtl_dump_bb: fix segfault when reporting internal error
During ICE reporting, sometimes rtl_dump_bb is called on partially
initialized basic blocks. This produces another ICE, obscuring the
original problem.
Fix by checking that that basic blocks are initialized before touching
their bb_infos.
gcc/ChangeLog:
2020-11-25 Ilya Leoshkevich <iii@linux.ibm.com>
* cfgrtl.c (rtl_bb_info_initialized_p): New function.
(rtl_dump_bb): Use rtl_bb_info_initialized_p before accessing bb
insns.
