            Bug ID: 167119
           Summary: [JSC] Handle parseInt in DFG / FTL for kraken
                    crypto-ccm
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

kraken crypto-ccm repeatedly calls parseInt function.
I think we have a chance to optimize it by handling it in DFG, because

1. typically the second `radix` parameter is constant! We typically call it in the form like `parseInt(xxx, 10)`. So in that case, many checks can be dropped.
2. typically the first parameter is string. We can use StringUse to avoid string type check & conversions in parseInt function.
