Revert r341342: Dwarf .debug section compression support (zlib, zlib-gnu).

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).
