ac23808619 [ELF] Add Readers for all the ELF subtargets.
This would permit the ELF reader to check the architecture that is being
selected by the linking process.

This patch also sorts the include files according to LLVM conventions.

2aae2b4609 [ELF] Fix incorrect sorting of .init_array / .fini_array sections.
The main problem is in the predicate passed to the `std::stable_sort()`.
This predicate always returns false if **both** section's names do not
start with `.init_array` or `.fini_array` prefixes. In short, it does not
define a strict weak orderng. Suppose we have the following sections:

  .A .init_array.1 .init_array.2

The predicate states that:

  not .init_array.1 < .A
  not .A < .init_array.2
  but .init_array.1 < .init_array.2 !!!

The second problem is that `.init_array` section without number should
go last in the list. Not it has the lowest priority '0' and goes first.

The patch fixes both of the problems.
