[PATCH] D92902: [llvm-elfabi] Add flag to keep timestamp when output is the same

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

`--preserve-dates` in this utility is different from `--preserve-dates` in GNU/LLVM objcopy, so I am a bit unsure this is the right name. In llvm-tblgen such an option is called `--write-if-modified`
