See https://discourse.llvm.org/t/rfc-enable-assignment-tracking/69399 This sets the -Xclang -fexperimental-assignment-tracking flag to the value enabled which means it will be enabled so long as none of the following are true: it's an LTO build, LLDB debugger tuning has been specified, or it's an O0 build (no work is done in any case if -g is not specified or -gmlt is used). This reverts commit 9e7f14a8211c82dca64bd6b22d1c450d4c6d3e5b which reverts https://reviews.llvm.org/D146987
