[PATCH] org-element.el; significant optimizations for org-element--interpret-affiliated-keywords

[Dwarshuis, Nathan J]

Hi all,

I noticed that calling `org-element-interpret-data' on objects is generally 
5-10x faster than when calling on elements. The reason seems to be that 
`org-element--interpret-affiliated-keywords' (which is only called on elements) 
does alot of unnecessary work. Namely, it runs on all elements (including those 
that should never have an affiliated keyword) and also loops over 
:standard-properties which should not be relevant here.

The attached patch addresses this.

I also attached some benchmarks pre and post-patch and accompanying code, which 
shows many elements (specifically those without children) approaching the 
execution time of objects. For the graphs, just pay attention to the 
'org-element' bars (red); the others were from me trying to optimize the 
`org-ml` package.

Thank you,
Nate
