RFR: 8358722: [leyden] Revert whitespace/comment diffs against mainline

[Aleksey Shipilev]

Not having extra whitespace/comments hunks against mainline makes merges simpler.  These are the extra hunks I notices when looking through Leyden-vs-mainline webrev.

Additional testing:
 - [x] Linux x86_64 server fastdebug, `runtime/cds`
