Hi Linus,

Please pull this var-init update for v5.9-rc1. (This is the tree formerly
known as "mem-init", which you correctly pointed out was not a good
name.) This adds the "zero" init option from Clang, which is being used
widely in production builds of Android and Chrome OS (though it keeps the
"pattern" init, which is better for debug builds).

Thanks!

-Kees
