           Summary: Remove unnecessary SpecialFastCaseProfiles.
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

The current baseline code creates special fast case profiles records for bytecodes that don't need them.  This was done to keep the DFG from crashing when it searches for such a profile and don't find one.  Instead, we should fix the code to check for the existence of the profile before dereferencing it to get a count.
