Add the --build-summary-exclude-informative flag.

It (in combination with --build-summary-only-diet) makes the
package:path summary is almost 3 times smaller, partially because of
skipping bodies, patially because of excluding documentation comments,
and partially because of making 'codeRange' fields informative.

We also remove MD5 hashes.

As I can see after changes in method bodies we generate the exactly
same file (or at least 'cmp -l' thinks so). Adding a new field results
in a file of different length.
