<pre>
    The following doc: https://mlir.llvm.org/docs/Tutorials/DataFlowAnalysis/ has gotten severely outdated after the more recent work on dataflow analysis framework (https://discourse.llvm.org/t/rfc-a-dataflow-analysis-framework/63340). As far as I can tell, the `ForwardDataFlowAnalysis` class referenced in the doc page no longer exist.

I found a doc update by @Mogball  here that was never merged: https://reviews.llvm.org/D128233. There were mentions that it has gone a little outdated, but nonetheless is more up-to-date than what's on the website currently. How much effort perhaps would it take to get this patch up-to-date & merged? (I'm happy to help or pick it up entirely)
