During inlining, remove POP instructions popping inlined lambdas

In cases like KT-17384, where 'break' or 'continue' happens in an argument
to an inlined lambda call, fix-stack transformation sees corresponding
ALOAD for lambda, and inserts corresponding POP instruction before jump.
However, this ALOAD is later removed during inlining.
So, we should also remove the related POP instructions.
