This is a reland of cfb100282e
with a fix for failures in lite mode.
Original change's description:
> [compiler] Cache OSR optimized code
>
> With lazy feedback allocation, for functions that get OSRed we may
> not have feedback for the initial part of the functions since feedback
> vectors might be allocated after the function started executing. Hence
> we would not be able to optimize the function on the next call. This
> means we may have to OSR twice before we actually optimize function.
> This cl introduces OSR cache, so we could reuse the optimized code. One
> side effect of this cl is that the OSRed code won't be function context
> specialized anymore.
