This patch updates the ORC layers and utilities to return and propagate llvm::Errors where appropriate. This is necessary to allow ORC to safely handle error cases in cross-process and remote JITing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@307350 91177308-0d34-0410-b5e6-96231b3b80d8
