breakpoint condition on other frames

[SOF3]

It would be useful to have breakpoints that can join conditions from multiple frames, e.g.

break <locspec>
cond 1 -frame 2 id == 1
cond 1 -and -frame 1 subId == 0

where -and appends the new condition to the previous condition instead of overwriting it, and -frame indicates the frame in which the expression is evaluated.

right now the alternative would be to use two breakpoints and operate manually:

break 1 <locspec>
frame 2
break 2 0
cond 2 id == 1
cond 1 false
continue
clear 2
cond -clear 1
continue
