I am adding testcases for compressed-debug sections.

I think we should also support compress/uncompress debug sections
with objcopy.

I think we can do

1. Uncompress debug section on read as an option.
2. Add a BFD function to compress debug sections.
3. Add lang_compress_sections and call it from
lang_process.

We may be able to share compress functions between
gas, ld and objcopy.

Thanks.
