Currently, setCgoAttr populates the cgo_export_{static,dynamic} maps with symbol names of exported symbols, which are then re-looked-up by deadcode and setupdynexp, which in turn puts the re-looked-up symbols in ctxt.dynexp. setCgoAttr already looked up the Syms, so simplify all of this by making setCgoAttr populate ctxt.dynexp directly and eliminating the cgo_export_{static,dynamic} maps. Recording Syms directly also sets us up to use correct symbol versions for these exports, rather than just assuming version 0 for all lookups. Since setupdynexp doesn't really do any "setting up" of dynexp any more with this change, we fold the remaining logic from setupdynexp directly into addexport, where it has better context anyway. This also eliminates a sorting step, since we no longer do a non-deterministic map iteration to build the dynexp slice. For #40724.
