Don't compare commit message against auto-merge commit

Browse Source 
When a merge commit is compared against its auto-merge commit, we want
to show the complete commit message as new in the diff screen (the
same as when the commit is compared against a parent commit).

Define a new class ComparisonType that encapsulates the information
about whether the comparison is done against a parent or against the
auto-merge.

If the comparison is done against a parent, include the parent number.
The parent number will be needed if we want to have magic files with
content that depends on the parent against which the comparison is
done. Include the parent number already now, so that we don't need to
invalidate the PatchListCache later once more.

Commenting on the auto-merge commit message is no longer possible.
Old comments that were done on the auto-merge commit message are
filtered out when comments are retrieved (because we don't return any
content to which they could be applied).
