Hi Paul,

Thank you for noticing this PR.

Yes, this patch adds C1 intrinsic supports for checkIndex, I will replace all variants of checkIndex with Objects.checkIndex in follow-up PRs.

It seems that Object.checkIndex can not meet our needs because it implicitly passes null to Preconditions.checkIndex, but we want to customize exception messages, so we might add extra APIs in Objects while doing the replacement.

Thank you Paul~
