// cgoUse is called by cgo-generated code (using go:linkname to get at
// an unexported name). The calls serve two purposes:
// 1) they are opaque to escape analysis, so the argument is considered to
// escape to the heap.
// 2) they keep the argument alive until the call site; the call is emitted after
// the end of the (presumed) use of the argument by C.

    (I hope that this workaround does not cause its own problems in the future.)
