Original issue's description:
> Rearrange SkRecord with small N in mind
>
> This rearranges the record pointers and types so they can go in a single array, then preallocates some space for them and for the SkVarAlloc.
>
> picture_overhead_draw bench drops from ~1000ns to 500-600ns, with no effect on picture_overhead_nodraw.
>
> I don't see any significant effect on large picture recording times from our .skps.
