Reviewed by Yusuke Suzuki.
The patch changes the logic that populates the instruction location map
(`instruction_locs`,
formerly `breakpoint_locs`) to direcly resolve the corresponding symbols
instead of relying on
instruction breakpoints being set. Additionaly, that is done lazily until
successful.
This apoproach handles the scenario when the `set_breakpoints` command is
issued before starting the
program, and breakpoint locations can't yet be unresolved. And of course, this
approach works
even if no instruction breakpoints are set.
We also distinguish between the top and the selected stack frames, which
handles the case when an
IPInt frame is not the top and we select it using `frame select`.
The patch also tweaks the presentation of ipint status to tighten it up and
make it easier to scan
visually.
