ZJIT removes redundant object loads and stores

Of all the facets of HN’s title autodestroy, I think removing “How” from titles is the worst one. I believe OP can edit it back in though.

(I passed over this article thinking it was a “look how mysteriously smart the mysteriously smart compiler is” acticle, not a “here’s how the smarts in a compiler work” one.)

curious if zjit will be ready to be default over yjit next ruby release. hope so!
