Is there a reason not to put these consecutive with struct5?

Caution mostly. If enum has explicitly assigned values, I assume that someone somewhere relies on them being exactly those values and it's prudent to extend the range rather than change existing order.

Fixed another place where we're checking the number of fields in a struct.

Ugh. Make sure static array to keep per-field info is also sized properly.

Replaced fixed-size array with SmallVector<>. One less place for making potential buffer overflow error when struct encoding changes.
