Display variable contents when exploring call stack

[tehKaiN]

Currently, only variables on the top of the callstack are visible. When navigating nested calls, their values are not displayed.

This would be especially helpful for some asserts triggering within nested function calls.

I think it might be related to -fomit-frame-pointer option, because according to docs it affects stack frames etc. Skipping it however makes my codebase unstable, especially static inline fns found in header files. Removing those keywords doesn't help, so I guess having .h is more of a culprit. I'll try investigating it a bit more, but here's what I get atm:

that only occurs in debug builds and not release/rel-with-debug. Funny thing is, the rel-with-debug freezes uae whenever the breakpoint is meant to be triggered, but the editor doesn't show anything and pause button doesn't help with it either.
