[PATCH] D35487: [ELF] - Represent .init_array/.fini_array via synthetic sections.

[George Rimar via Phabricator via llvm-commits]

grimar created this revision.
Herald added a subscriber: emaste.

I suggest this change, it should open road for fixing PR31224.
This patch introduces InitFiniSection which holds
.init_array/.fini_array sections inside.

Idea is next: we can do the same for .ctors/.dtors in another patch. 
Synthetic section for .ctors/.dtors should know how to
change sorting rules on fly depending on output section name.

Then it should be possible to mix .init_array/.ctors and .fini_array/.dtors,
like bfd/gold do easily.
