This patch replaces most of the Orc indirection utils API with a new class: JITCompileCallbackManager, which creates and manages JIT callbacks. Exposing this functionality directly allows the user to create callbacks that are associated with user supplied compilation actions. For example, you can create a callback to lazyily IR-gen something from an AST. (A kaleidoscope example demonstrating this will be committed shortly). This patch also refactors the CompileOnDemand layer to use the JITCompileCallbackManager API. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229461 91177308-0d34-0410-b5e6-96231b3b80d8
