Description

I had a small use case in swift-format where I wanted to check the precedence of an operator relative to another one (swiftlang/swift-format#647).

Unfortunately there's no public API to do this from OperatorTable; the logic is inside PrecedenceGraph, which is internal. Can we have this API or something like it in public form?

I wouldn’t be opposed to adding a public function to perform this comparison on OperatorTable.

Thanks! It's not an urgent need but I'll tinker with it and put up a PR.
