Craig Topper 88feba99f6 [RISCV] Teach DAG combine what bits Zbp instructions demanded from their inputs. 
This teaches DAG combine that shift amount operands for grev, gorc
shfl, unshfl only read a few bits.

This also teaches DAG combine that grevw, gorcw, shflw, unshflw,
bcompressw, bdecompressw only consume the lower 32 bits of their
inputs.

In the future we can teach SimplifyDemandedBits to also propagate
demanded bits of the output to the inputs in some cases.

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.
