LLVM <= 4.0 used a non-standard interpretation of `DW_OP_plus`. In the DWARF standard, this adds two items on the expressions stack. LLVM's behavior was more like DWARF's `DW_OP_plus_uconst` -- adding a constant that follows the op. The patch series starting with [D33892] switched to the standard DWARF interpretation, so we need to follow. [D33892]: https://reviews.llvm.org/D33892
