The legacy GASNet-1 backend has been superseded by the new GASNet-EX backend, which has been Chapel's default GASNet backend since 658ac15 (Chapel 2.1). Both backends run over the same GASNet-EX implementation, so this is mostly just about removing pointlessly duplicated Chapel runtime code, to improve future maintainability. Deliberately undocumented setting `CHPL_GASNET_VERSION` is also removed. Partially reverts 2f4776e Signed-off-by: Dan Bonachea <[email protected]>
