Clemens Hammacher d7e59efa35 Revert "Reland: [Compiler] Use CompilationCache for StreamedScript compilation." 
This reverts commit 2542720357.

Reason for revert: code-coverage failures on gc-stress bot: https://build.chromium.org/p/client.v8/builders/V8%20Linux64%20GC%20Stress%20-%20custom%20snapshot/builds/17956

Original change's description:
> Reland: [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.
> 
> Also refactors the compilation pipelines to ensure we call debug->OnAfterCompile()
> for all script compiles even when loading from a cache.
