  Log Message:
  -----------
  Fix -Wunused-result warnings in LLDB

Three uses of try_lock intentionally ignore the result, as explained in
the comment. Make that explicit with a void cast.

Add what appears to be a missing return in the clang expression parser
code. It's a functional change, but presumably the right one.
