Switch a vector<pair<const T &, const U &>> to a vector<pair<const T *,
...
const U *>>. Even in C++11 it doesn't seem this is valid as vector's
emplace support requires move assignment, and there is no way to move
assign a reference.
The real motivation however is that this fixes the build of lld with
libstdc++ 4.6.

[ELF][Writer] Refactor Section to not have atoms. Move atoms into AtomSection.
...
The purpose of this change is to simplify creating non-atom sections.
Previously _contentType, _sectionKind and _order were used for multiple
purposes and collided in places. This moves all of the Atom specific logic down
into AtomSection and makes Section just have raw Elf_Shdr flags.

[ELF][x86-64] Fix ifunc and add test.
...
In an previous commit I managed to completely disable the IRELATIVE relocation
writing code. I also used the wrong addend for the static relocation. Fix both
these issues and add a test. This test is quite brittle because there's no way
to do arithmetic on variables in FileCheck.
