@magabari - what is the status of this patch?

We have another potential motivating example for ignoring overflow (specifically of sdiv by -1) in PR38239:
https://bugs.llvm.org/show_bug.cgi?id=38239

...because sdiv has that extra UB potential from a -1 divisor that doesn't exist for udiv, we can't do the sibling optimization that we did for udiv.
