Interesting, it looks like the difference here is almost entirely due to different inlining decisions.

And according to the tool I posted here:
http://lists.llvm.org/pipermail/llvm-dev/2019-April/131811.html
in the few functions in which we made the same inlining decisions, the -Oz assembly is almost always smaller.
