When using a SequenceChecker, this adds a bit more information
about why the check failed.
Example (The "Expects" line is new):
# Fatal error in: foo.cc, line 380
# last system error: 0
# Check failed: (&thread_checker_)->IsCurrent()
# Expects: System queue: 0x7fff69541330, TaskQueue: 0x101804370 (not current), Thread: 0x10053cdc0
