1. symbolizer: cache each DWARF DIE's nextOffset and nextSiblingOffset …

   This avoids exponential growth in runtime when parsing deeply nested debug info. The scenario that would otherwise lead to exponential growth involves `forEachChild()` with an argument lambda that itself recurses into children. At each layer of depth, `forEachChild()` iterates over all indirect children (to skip them) and so does the argument lambda (to process the top-level ones and recurse on their children). So each top-level DIE is visited twice, each second-level is visited four times, each third-level one is visited eight times, and so on.
