[PATCH 0/4] Fix CU expansion queue-related problems

This patch series fixes problems explained in PR 26828 [1].  The
problems are related to CU DIEs loading/freeing and the CU expansion
queue.  All the gory details are in the commit logs.

I tried to write a test case for this using the DWARF assembler but I
couldn't manage to do it.  I decided to submit the series anyway,
because I'd still like to fix the issue.  I might try again later, but I
might also not have the time, so if anybody would like to give it a try,
you are welcome.

Simon Marchi (4):
  gdb/dwarf: add some logging in dwarf2/read.c
  gdb/dwarf: add assertion in maybe_queue_comp_unit
  gdb/dwarf: don't enqueue CU in maybe_queue_comp_unit if already
    expanded
  gdb/dwarf: create and destroy dwarf2_per_bfd's CUs-to-expand queue
