fix! loops in preprocess_use_blocks iterate to the wrong bound0.0.1

A token_stream being constructed on the spot has different
used/available properties to a fully constructed one: a fully
constructed token stream uses available to hold the total number of
tokens and used as an internal iterator, while one that is still being
constructed uses the semantics of a standard darr.

Furthermore, some loops didn't divide by ~sizeof(token_t)~ which lead
to iteration over bound errors.
