Now that we have new DWARF Rewriter we can remove DW_AT_low_pc when converting DW_AT_low_pc/DW_AT_high_pc to DW_AT_ranges. Which closer follows DWARF spec. Leaving CU DW_AT_low_pc in place. Reading the spec I think it's needed. Reviewed By: maksfb Differential Revision: https://reviews.llvm.org/D156957
