mvstanton 14fa68a305 Revert of PPC: Type Feedback Vector lives in the closure (patchset #1 id:1 of https://codereview.chromium.org/1671553002/ ) 
Reason for revert:
issues with chromium api natives, must revert for now, thanks.

Original issue's description:
> PPC: Type Feedback Vector lives in the closure
>
> Port bb31db3ad6
>
> Original commit message:
>     (RELAND: the problem before was a missing write barrier for adding the code
>     entry to the new closure. It's been addressed with a new macro instruction
>     and test. The only change to this CL is the addition of two calls to
>     __ RecordWriteCodeEntryField() in the platform CompileLazy builtin.)
>
>     We get less "pollution" of type feedback if we have one vector per native
>     context, rather than one for the whole system. This CL moves the vector
>     appropriately.
>
>     We rely more heavily on the Optimized Code Map in the SharedFunctionInfo. The
>     vector actually lives in the first slot of the literals array (indeed there is
>     great commonality between those arrays, they can be thought of as the same
>     thing). So we make greater effort to ensure there is a valid literals array
>     after compilation.
>
>     This meant, for performance reasons, that we needed to extend
>     FastNewClosureStub to support creating closures with literals. And ultimately,
>     it drove us to move the optimized code map lookup out of FastNewClosureStub
>     and into the compile lazy builtin.
>
>     The heap change is trivial so I TBR Hannes for it...
>     Also, Yang has had a look at the debugger changes already and approved 'em. So he is TBR style too.
>     And Benedikt reviewed it as well.
