[PATCH] D20211: [ELF] - Support of compressed debug sections sections (draft).

[George Rimar via llvm-commits]

This is a draft patch to support creation of all possible types of compressed debug sections.
Patch does not have testcases yet, I am going to update it soon, tomorrow probably.
Would be happy to hear any suggestions/opinions.

A bit belated question, probably: are we going to support that ? That is relatively
new feature, but both bfd/gold do.
