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.

Also reverts follow-up commits r341343 and r341344.
The primary commit continues to break some build bots even after the
fixes in r341343 for UBSan issues:
http://lab.llvm.org:8011/builders/clang-cmake-aarch64-full/builds/5823
It is also failing for me locally (linux, x86-64).
