Craig Topper 9ed3d57a44 [RISCV] Add a vsetvli insert pass that can be extended to be aware of incoming VL/VTYPE from other basic blocks. 
This is a replacement for D101938 for inserting vsetvli
instructions where needed. This new version changes how
we track the information in such a way that we can extend
it to be aware of VL/VTYPE changes in other blocks. Given
how much it changes the previous patch, I've decided to
abandon the previous patch and post this from scratch.

For now the pass consists of a single phase that assumes
the incoming state from other basic blocks is unknown. A
follow up patch will extend this with a phase to collect
information about how VL/VTYPE change in each block and
a second phase to propagate this information to the entire
function. This will be used by a third phase to do the
vsetvli insertion.

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.
