Nick Mathewson 4753ad4f1d Add a script to compare directories full of gcov output
We can't just use "diff", since we don't care about changes in line
numbers, or changes in the exact number of times a line was called.
We just care about changes that make lines covered or non-coverd.  So
pre-process the files before calling diff.
