Alexander Potapenko d0446d3d9b [MSan] Add KMSAN instrumentation to MSan pass 
Introduce the -msan-kernel flag, which enables the kernel instrumentation.

The main differences between KMSAN and MSan instrumentations are:

- KMSAN implies msan-track-origins=2, msan-keep-going=true;
- there're no explicit accesses to shadow and origin memory.
  Shadow and origin values for a particular X-byte memory location are
  read and written via pointers returned by
  __msan_metadata_ptr_for_load_X(u8 *addr) and
  __msan_store_shadow_origin_X(u8 *addr, uptr shadow, uptr origin);
- TLS variables are stored in a single struct in per-task storage. A call
  to a function returning that struct is inserted into every instrumented
  function before the entry block;
- __msan_warning() takes a 32-bit origin parameter;
- local variables are poisoned with __msan_poison_alloca() upon function
  entry and unpoisoned with __msan_unpoison_alloca() before leaving the
  function;
- the pass doesn't declare any global variables or add global constructors
  to the translation unit.

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.
