Optimise size calculation for binary construction
It turns out it was extremely common to have a following sequence: move 0 D1 byte_size _ D2 bs_add D1 D2 D Which is equivalent to just: byte_size _ D Similarly another sequence: move S D1 byte_size _ D2 bs_add D1 D2 D Can be optimised into: byte_size _ D2 bs_add S D2 D Both of those optimisations work with byte_size and bit_size instructions.
