FYI this caused failed builds for aarch64 (when building with `-fno-signed-zeros`), hitting unreachable statements in TargetLowering::getNegatedExpression - see https://bugs.llvm.org/show_bug.cgi?id=44892. I guess that's a bug in the aarch64 backend and not with this change in itself, but it was only uncovered by this change...
