[Debuginfo][llvm-dwarfutil] Add check for unsupported debug sections.
Current DWARFLinker implementation does not support some debug sections
(mainly DWARF v5 sections). This patch adds diagnostic for such sections.
The warning would be displayed for critical(such that could not be removed)
sections and the source file would be skipped. Other unsupported sections
would be removed and warning message should be displayed. The zero exit
status would be returned for both cases.

[Reland][DebugInfo][llvm-dwarfutil] Combine overlapped address ranges.
DWARF files may contain overlapping address ranges. f.e. it can happen if the two
copies of the function have identical instruction sequences and they end up sharing.
That looks incorrect from the point of view of DWARF spec. Current implementation
of DWARFLinker does not combine overlapped address ranges. It would be good if such
ranges would be handled in some useful way. Thus, this patch allows DWARFLinker
to combine overlapped ranges in a single one.
Depends on D86539

[Reland][Debuginfo][llvm-dwarfutil] llvm-dwarfutil dsymutil-like tool for ELF.
This patch implements proposal https://lists.llvm.org/pipermail/llvm-dev/2020-August/144579.html
llvm-dwarfutil - is a tool that is used for processing debug info(DWARF) located in built binary files to improve debug info quality, reduce debug info size. The patch currently implements smaller set of command-line options(comparing to the proposal):
```
./llvm-dwarfutil [options] <input file> <output file>
--garbage-collection Do garbage collection for debug info(default)
-j <value> Alias for --num-threads
--no-garbage-collection Don`t do garbage collection for debug info
--no-odr-deduplication Don`t do ODR deduplication for debug types
--no-odr Alias for --no-odr-deduplication
--no-separate-debug-file
Create single output file, containing debug tables(default)
--num-threads <threads> Number of available threads for multi-threaded execution. Defaults to the number of cores on the current machine
--odr-deduplication Do ODR deduplication for debug types(default)
--odr Alias for --odr-deduplication
--separate-debug-file Create two output files: file w/o debug tables and file with debug tables
--tombstone [bfd,maxpc,exec,universal]
Tombstone value used as a marker of invalid address(default: universal)
=bfd - Zero for all addresses and [1,1] for DWARF v4 (or less) address ranges and exec
=maxpc - Minus 1 for all addresses and minus 2 for DWARF v4 (or less) address ranges
=exec - Match with address ranges of executable sections
=universal - Both: bfd and maxpc
```
