[REQUEST]: LLVM-IR suggested enhancements

[OfekShilon]

Is your feature request related to a problem? Please describe

The LLVM-IR contents somewhat lag behind the shiny and new llvm-opt-pipeline view.

Describe the solution you'd like

(1) When LLVM-IR view is active, it would be helpful to build with -fno-discard-value-names. This (most of the time) preserves var names in the IR.

(2) It would be helpful to add the filter checkboxes from llvm-opt-pipeline pane, to optionally declutter the view. At least the removal of debug info is very useful.

Thanks for all your great work!

Describe alternatives you've considered

Sorry I see now that the -fno-discard is a default-on option in the opt-pipeline:

It would be just great just to have the same options and filters (besides 'hide inconsequential passes') on the llvm-ir display.

Thanks for the report, I've had in mind improving the llvm-ir pane for a while now, still on the backlog :) Filters, demangling, and -fno-discard-value-names would be good and happy to do anything else you can think of.

I'd like to rework some stuff in the backend to allow control flow graphs for llvm ir to be generated too, and when that happens we can add a button for opening a cfg pane.

[OfekShilon]

@jeremy-rifkin that would be awesome. Perhaps it would be feasible to add data-dependency-graphs too?

[jeremy-rifkin]

Data dependency graphs are a good idea, we could definitely do something like that. And for assembly too.

Will divert to #1158 for data-flow / data-dependency stuff
