VM Debugger improvement with IR

[QDucasse]

Improvement of the VM machine code debugger with the following changes:

• Automated refresh of the columns (no need to click to refresh)
• Added abstract instructions in a column on the left
• Clicking on an abstract instruction shows the corresponding machine code instruction(s)
• Clicking on a machine code instruction shows the corresponding affected register(s)

Note that the mc <-> registers highlights have been tried with ARMv8 and RISC-V but could be applied to any other ISA as long as the register aliases are correctly defined.

Cool, this is so nice

I've changed the base branch to Pharo X (and we should work in there in the future). I'll check the conflict.

I have the feeling that we will need to manually test after the merge :/. I've made some non-obvious merges.

I confirm this is working on the latest version.

I will test with a more complex method IR and push it if ok!

It seems that

• we have the stack and and registers panes duplicated
• the IR <-> machine code mapping is not working in the UI

I've made a pass, this is how it looks now:

I'll merge it, thanks @QDucasse !!!!
