[DebugInfo] Do not generate address info for removed debug labels.
In some senario, LLVM will remove llvm.dbg.labels in IR. For example,
when the labels are in unreachable blocks, these labels will not
be generated in LLVM IR. In the case, these debug labels will have
address zero as their address. It is not legal address for debugger to
set breakpoints or query sources. So, the patch inhibits the address info
(DW_AT_low_pc) of removed labels.
Fix build failed in BuildBot, clang-stage1-cmake-RA-incremental, on macOS.
