This patch adds the -Xclang option "-fexperimental-debug-variable-locations" and same LLVM CodeGen option, to pick which variable location tracking solution to use. Right now all the switch does is pick which LiveDebugValues implementation to use, the normal VarLoc one or the instruction referencing one in rGae6f78824031. Over time, the aim is to add fragments of support in aid of the value-tracking RFC: http://lists.llvm.org/pipermail/llvm-dev/2020-February/139440.html also controlled by this command line switch. That will slowly move variable locations to be defined by an instruction calculating a value, and a DBG_INSTR_REF instruction referring to that value. Thus, this is going to grow into a "use the new kind of variable locations" switch, rather than just "use the new LiveDebugValues implementation".
