Similar to r315841, GlobalISel and SelectionDAG require different code for the common atomic predicates due to differences in the representation. Even without that, differences in the IR (SDNode vs MachineInstr) require differences in the C++ predicate. This patch moves the implementation of the common atomic predicates related to memory type into tablegen so that it can handle these differences. It's NFC for SelectionDAG since it emits equivalent code and it's NFC for GlobalISel since the rules involving the relevant predicates are still rejected by the importer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@318095 91177308-0d34-0410-b5e6-96231b3b80d8
