¶bool isValidAsAccessGroup(llvm::MDNode* AccGroup)

Description

Return whether an MDNode might represent an access group. Access group metadata nodes have to be distinct and empty. Being always-empty ensures that it never needs to be changed (which -- because MDNodes are designed immutable -- would require creating a new MDNode). Note that this is not a sufficient condition: not every distinct and empty NDNode is representing an access group.
