[Bug middle-end/30768] [4.3 regression]: ICE in ext/pb_ds/regression/list_update_data_map_rand.cc

I have reproduced this with the attached .ii file and a cross-compiler to
cris-axis-elf.  The problematic function is allocate_new_entry.

I believe that the problem is that the dom2 pass eliminates basic blocks,
without updating n_basic_blocks.

In particular, looking at allocae_new_entry in 067t.copyrename3, I see 14 basic
blocks for allocate_new_entry.  In contrast, in 68t.dom2, I see 12.  When the
apply_inline pass runs later, it trips on the assert because it finds only 12
basic blocks -- but n_basic_blocks is 14.

Diego, is this something that you might be able to help with?  I'm not eager to
go tearing through dom trying to work this out, though I will if necessary, of
course...
