Sander de Smalen 6c6d96e619 [NFCI] Add StackOffset class and base classes for ElementCount, TypeSize. 
This patch adds a linear polynomial base class, called LinearPolyBase, which
serves as a base class for StackOffset. It tries to represent a linear
polynomial like:

  c0 * scale0 + c1 * scale1 + ... + cK * scaleK

where the scale is implicit, meaning that only the coefficients are
encoded.

This patch also adds a univariate linear polynomial, which serves as
a base class for ElementCount and TypeSize. This tries to represent a
linear polynomial where only one dimension can be set at any one time,
i.e. a TypeSize is either fixed-sized, or scalable-sized, but cannot be
a combination of the two.

  class LinearPolyBase
     ^
     |
     +---- class StackOffset  (dimensions = 2 (fixed/scalable), type = int64_t)

  class UnivariateLinearPolyBase
     |
     |
     +---- class LinearPolySize (dimensions = 2 (fixed/scalable))
                  ^
                  |
                  +-------- class ElementCount  (type = unsigned)
                  |
                  |
                  +-------- class TypeSize      (type = uint64_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.
