Issue Description
_stack_peephole_opts() tries to perform 5 different optimizations at
each index i of the assembly using a while loop. However, the last two
optimizations, when performed do not continue the loop, which means
that:
i is incremented by 1, leading to skipping the next instruction
and potentially missing an optimization.
If both optimizations are performed for a given i, it might be
that the second one tries accessing an index that is out of range
given that the first one removed the 2 last elements of the array
and the check for the index is not performed in between the two
optimizations.
