Detailed Description

The chunks of [0, num_samples), consecutive and at most kSnapChunkSamples long, as a range.

The caller snaps its register-resident state at the end of each chunk.

A range rather than a callback on purpose: a loop body passed as a lambda that captures a pass's state arrays by reference kept that state in memory instead of registers and made an eight-section cascade measurably slower; the range-for keeps the body in the caller's own scope.

for (const auto [begin, end] : snap_chunks(n)) {
    for (std::size_t i = begin; i < end; ++i)
        s = recursion(s, buffer[i]);
    s = snap_to_zero(s);
}
