deps: V8: cherry-pick b9d33036e9a8
Original commit message: [coverage] Improve whitespace precision of coverage reporting This CL improves whitespace precision of coverage around try blocks; previously a small portion of whitespace could be reported as uncovered between try blocks and catch and/or finally blocks.
