Craig Topper 1b47a3de48 [RISCV] Enable cross basic block aware vsetvli insertion
This patch extends D102737 to allow VL/VTYPE changes to be taken
into account before adding an explicit vsetvli.

We do this by using a data flow analysis to propagate VL/VTYPE
information from predecessors until we've determined a value for
every value in the function.

We use this information to determine if a vsetvli needs to be
inserted before the first vector instruction the block.

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.
