This patch introduces RemoteObjectClientLayer and RemoteObjectServerLayer, which can be used to forward ORC object-layer operations from a JIT stack in the client to a JIT stack (consisting only of object-layers) in the server. This is a new way to support remote-JITing in LLVM. The previous approach (supported by OrcRemoteTargetClient and OrcRemoteTargetServer) used a remote-mapping memory manager that sat "beneath" the JIT stack and sent fully-relocated binary blobs to the server. The main advantage of the new approach is that relocatable objects can be cached on the server and re-used (if the code that they represent hasn't changed), whereas fully-relocated blobs can not (since the addresses they have been permanently bound to will change from run to run). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@312511 91177308-0d34-0410-b5e6-96231b3b80d8
