Message:

It should be possible to hijack IndexingHeader for things other than lengths

Reviewed by Mark Hahnenberg.

Made the body of IndexingHeader be a union.

Modified the offlineasm so that you can say IndexingHeader::u.lengths.publicLength.
Previously those dots would cause parse errors. Now an identifier in offlineasm can
have a dot anywhere except the first character.
