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
