btrace: compute line range when printing

The "record function-call-history" command prints the range of source lines
for a function segment when given the /l modifier.  This information is
computed for the entire execution history when processing the recorded branch
trace.

To speed up the initial trace processing, we compute the information when
we print a function segment and only if requested.  The computation is fast
enough (due to the limited scope) that it is not worth storing the data in
struct btrace_function, anymore.
