[issue42899] Is it legal to eliminate tests of a value, when that test has no effect on control flow?

Thank you Steve. Yes, this is what I meant. "if a and b" is so common that we sacrifice literal translation for the sake of performance.

"if" with an empty block looks pretty uncommon to me. It is not worth to optimize this case specially (especially if it changes semantic). What are real world examples for which it makes sense to replace POP_JUMP_IF_FALSE with POP_TOP?
