250bfb1745 Remove the LLVM specific archive index.
Archive files (.a) can have a symbol table indicating which object
files in them define which symbols. The purpose of this symbol table
is to speed up linking by allowing the linker the read only the .o
files it is actually going to use instead of having to parse every
object's symbol table.

LLVM's archive library currently supports a LLVM specific format for
such table. It is hard to see any value in that now that llvm-ld is
gone:

* System linkers don't use it: GNU ar uses the same plugin as the
linker to create archive files with a regular index. The OS X ar
creates no symbol table for IL files, I assume the linker just parses
all IL files.

* It doesn't interact well with archives having both IL and native objects.

* We probably don't want to be responsible for yet another archive
format variant.

This patch then:

* Removes support for creating and reading such index from lib/Archive.
* Remove llvm-ranlib, since there is nothing left for it to do.

We should in the future add support for regular indexes to llvm-ar for
both native and IL objects. When we do that, llvm-ranlib should be
reimplemented as a symlink to llvm-ar, as it is equivalent to "ar s".

9f8e6da019 Require members of llvm.used to be named.
The effect of llvm.used is to introduce an invisible reference, so this seems
a reasonable restriction. It will be used to provide an easy ordering of
the entries in llvm.used.

2dce4f27ef Update code listings in LLVM tutorial.
Several LLVM headers are moved.  The code listings in
LLVM tutorial are not updated yet.

This CL removes the code replica in the .rst, and replace
them with a literalinclude directive, so that sphinx can
include the latest code automatically.

2e24e19cac Better output for long help strings for command-line options.
Summary:
This patch allows using \n inside long help strings for command-line
options, so that all lines are equally indented. This is not a perfect solution,
as we don't (and probably don't want to) know about terminal width, but it
allows to format long help strings somehow readable without manually padding
them with spaces. A motivating example is -help output from clang-format (source
code in tools/clang-format/ClangFormat.cpp, see cl options offset, length,
style, and dump-config).
