[v2] Fix the reporting of leaf change statistics.
Commit Message
Leaf changes (as reported with --leaf-changes-only) to variables were
miscounted as changes to functions.
* src/abg-comparison.cc
(apply_filters_and_compute_diff_stats): Increment the correct
counter for leaf variable changes.
* tests/data/Makefile.am: Add test case files.
* tests/data/test-abidiff-exit/test-leaf0-*: New test case.
* tests/test-abidiff-exit.cc: Run new test case.

I assume the sources of those are rather small, so can you add the
source snippets of the test files to the commit message?

Should the variable change not be reported as well? Is this a different
issue or are variables changes are not supposed to be reported in this
mode?

Should we also add a test case to the default mode (not leaf changes),
to ensure consistency?
Thanks!

The file is named test-leaf0-report.txt
With that, `make distcheck` runs successfully as well.
