Alexander Yermolovich efb8a1c906 [BOLT][DWARF] Delete DW_AT_low_pc when converting to ranges
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.
