[PATCH] D87197: [InstSimplify] Fold degenerate abs of abs form

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

It doesn't matter that the constant is 0 specifically, does it?  Should work for any constant besides INT_MIN with the correct sign.

Is it worth trying to generalize this?  It seems like something along the lines of SimplifyWithOpReplaced should be able to simplify this.
