This patch attaches the descriptive names to private internal functions in JSC to make it visible in sampling profiler etc.

       146    'slice#<nil>:None:<nil>'
       117    'indexOf#<nil>:None:<nil>'
       111    'anonymous#EWjJWT:Baseline:bc#1'

After:
    Hottest bytecodes as <numSamples   'functionName#hash:JITType:bytecodeIndex'>
