[libcxx-commits] [libcxx] Optimize input_iterator-pair `insert` for std::vector (PR #113768)

[Louis Dionne via libcxx-commits]

This LGTM with a small nitpick about adding a comment, and a suggestion to optimize further. Given I have no more feedback, I actually suggest that we land the patch after my nitpick comment and investigate further optimizations in later patches, to unblock this work and make sure we hit LLVM 20.

Thanks for the great patch!
