This change fixes incorrect lane ordering in reinterpretation operations on big-endian platforms. When converting from wider to narrower lane types like Long to Int, Long to Short, big-endian systems produced reversed sub-lanes. The patch adds a maybeSwapOnConverted() and a generic normalizeSubLanesForSpecies() shuffle builder to correct the sub-lane order based on element sizes on big-endian
