bytes: make all readOp constants actually typed

Browse Source 
This is a regression introduced in golang.org/cl/28817. That change got
rid of the iota, which meant that the type was no longer applied to all
the constant names.

Re-add the iota starting at -1, simplifying the code and adding the
types once more.
