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.
