Puyan Lotfi ac820be777 [llvm-objcopy] Dwarf .debug section compression support (zlib, zlib-gnu).
Third Attempt:
    - Alignment issues resolved.
    - zlib::isAvailable() detected.
    - ArrayRef misuse fixed.

  Usage:

  llvm-objcopy --compress-debug-sections=zlib foo.o
  llvm-objcopy --compress-debug-sections=zlib-gnu foo.o

  In both cases the debug section contents is compressed with zlib. In the GNU
  style case the header is the "ZLIB" magic string followed by the uint64 big-
  endian decompressed size. In the non-GNU mode the header is the
  Elf(32|64)_Chdr.

  Decompression support is coming soon.
