Nikita Popov 00449b7b7f [ValueTracking] Move constant range computation into ValueTracking; NFC 
InstructionSimplify currently has some code to determine the constant
range of integer instructions for some simple cases. It is used to
simplify icmps.

This change moves the relevant code into ValueTracking as
llvm::computeConstantRange(), so it can also be reused for other
purposes.

In particular this is with the optimization of overflow checks in
mind (ref D59071), where constant ranges cover some cases that
known bits don't.

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
