Allow giving friendly names to registers/addresses

[mattbruv]

This would be a quality of life feature. When looking at the source assembly, it would be cool to be able to right click and assign a name to register(s) or address(es) that would appear when you select that register/address.

Let's say in this example I recognize that address 3c is the end of a loop. It would be nice to be able to tag it and give it a name such as end of loop.

This would help me not to have to keep as much context in my head when working on bigger functions.

This is the exact reason you use a tool like IDA or Ghidra, it's named the Interactive DisAssembler for a reason. At some point, objdiff should be limited in scope. Maybe it's time for Ghidra integration plugin instead?

I like using objdiff much more than Ghidra 🤷
