Add a mechanism to permit plugins running code between optimizations and the back-end passes. Implement this through the LLVM plug-in mechanism to make permit plugins to be written independently of the front-end. The primary motivation for this point is TPDE-LLVM, which substitutes the LLVM back-end (optionally falling back to it for unsupported IR). We have been distributing a Clang patch; but requiring a custom-build toolchain is impracticable for many users. Front-end adjustments will follow as separate patches.
