When generating callgrind format output, produce cost lines at instruction granularity. This allows visualizers supporting the callgrind format to display instruction-level profiling information. We also need to provide the object file (ob=) in order for tools to find the object file to disassemble when displaying assembly. We opportunistically group cost lines corressponding to the same function together, reducing the number of superfluous description lines. Subposition compression (relative position numbering) is also used to reduce the output size.
