Jump tables - ask dialog for amount of elements

[lab313ru]

It would be great to add asking of jump table elements count for situations, if program cannot identify how much elements this jump table contains.

Good suggestion! I'm thinking that reko should show a Warning, and if you click on the warning, you get the dialog where you specify the jump table bounds.

I've made changes to the Reko GUI so that if you get a warning to the effect of "unable to resolve jump table", you can double click it and a dialog pops up, looking like this:

Note that the feature is not yet complete, but is a prototype. If you have the time, play with the dialog and then add comments and suggestions here.
