Reverted in 98fa95492f3bbd5befdeb36c88a3ac5ef2740b4e. The Assignment Tracking debug-info feature is outlined in this RFC: https://discourse.llvm.org/t/ rfc-assignment-tracking-a-better-way-of-specifying-variable-locations-in-ir This patch plumbs the AssignmentTrackingPass (AKA declare-to-assign), added in the previous patch in this set, into the optimisation pipeline from clang. clang/test/CodeGen/assignment-tracking/assignment-tracking.cpp is the main test for this patch. Note: while clang (with the help of the declare-to-assign pass) can now emit Assignment Tracking metadata, the llvm middle and back ends don't yet understand it.
