Michael Achenbach 5fcf508e07 Revert "[TypeFeedbackVector] Store optimized code in the vector" 
This reverts commit c5ad9c6d8e.

Reason for revert: Fails on gc stress:
https://build.chromium.org/p/client.v8/builders/V8%20Linux64%20GC%20Stress%20-%20custom%20snapshot/builds/12661

Original change's description:
> [TypeFeedbackVector] Store optimized code in the vector
> 
> Since the feedback vector is itself a native context structure, why
> not store optimized code for a function in there rather than in
> a map from native context to code? This allows us to get rid of
> the optimized code map in the SharedFunctionInfo, saving a pointer,
> and making lookup of any optimized code quicker.
> 
> Original patch by Michael Stanton <mvstanton@chromium.org>
> 
> BUG=v8:6246
