Original change's description:
> [Compiler] Use CompilationCache for StreamedScript compilation.
> 
> Previously GetSharedFunctionInfoForStreamedScript didn't either check the
> compilation cache or put the result of compilation into the compilation
> cache. This would mean future compiles would need to re-parse / compile
> the same script even if the isolate had already seen it. This CL
> fixes this.
