Description
Right now we show the variables removed by dead-store elimination with a dimmed color. Which is good in most cases, however, sometimes we might wish to have the removed completely.
I have seen a binary that, for unknown reason, always moves the frame pointer 0x1000 below the stack pointer (at the function entry). I do not exactly understand what is trying to do.
Right now it is causing an inconvenience that the useful part of the stack are all outside of the bottom of the view by default, and I have to scroll to it to see its content. If we can limit the stack to all the used vars, the situation would be much better

Research direction
Start by inspecting the stack view and disassembly view handling for variables removed by dead-store elimination, including where their dimmed presentation is configured. Determine how a visibility option could apply to both views and verify that the useful stack range is shown when removed variables are hidden.
