-1.  If PVS-Studio is complaining about this type of coding, to hell with
it; it should just optimize away the extra tests and be quiet about it,
not opinionate about coding style.  What you propose would cause logically
independent pieces of code to become tied together, and I don't find that
to be an improvement.  It's the compiler's job to micro-optimize where
possible, and most compilers that I've seen will do that rather than tell
the programmer he ought to do it.
