Extend TargetPassConfig to allow running only a subset of the normal passes. This is still a work in progress but I believe it is currently good enough to fix PR13122 "Need unit test driver for codegen IR passes". For example, you can run llc with -stop-after=loop-reduce to have it dump out the IR after running LSR. Serializing machine-level IR is not yet supported but we have some patches in progress for that. The plan is to serialize the IR to a YAML file, containing separate sections for the LLVM IR, machine-level IR, and whatever other info is needed. Chad suggested that we stash the stop-after pass in the YAML file and use that instead of the start-after option to figure out where to restart the compilation. I think that's a great idea, but since it's not implemented yet I put the -start-after option into this patch for testing purposes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159570 91177308-0d34-0410-b5e6-96231b3b80d8

Remove the Forward Control Flow Integrity pass and its dependencies. This work is currently being rethought along different lines and if this work is needed it can be resurrected out of svn. Remove it for now as no current work in ongoing on it and it's unused. Verified with the authors before removal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230780 91177308-0d34-0410-b5e6-96231b3b80d8
