Handle frame pointer omission (#21), part 3: SourceLineResolver and PDBSourceLineWriter changes. r=bryner.
- PDBSourceLineWriter (dump_syms) outputs stack frame debugging information
- SourceLineResolver reads the new information and puts it into a
new StackFrameInfo structure, which is stored in a ContainedRangeMap.
FillSourceLineInfo passes the StackFrameInfo back to the caller.
- The base Stackwalker makes StackFrameInfo data available to subclasses
during stackwalking, but does not use this information directly itself.
Stackwalkers may access stack_frame_info_ for enhanced stackwalking
(this will be part 4).
- New test data for the updated dumped-symbol format
