Proof step 12 from proof int2bits-leneq-neg (previous step)

j < 0 ⊦ ¬ 0 ≤ j + 2 ^ (n→i(# int2bits(j)) - 2), # int2bits(j) = 1

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 13:
0 ≤ j + 2 ^ (n→i(# int2bits(j)) - 2), j < 0 ⊦ # int2bits(j) = 1

Rule argument
