Michael Liao d21f701c76 [MIRPrinter] Add machine metadata support. 
- Distinct metadata needs generating in the codegen to attach correct
  AAInfo on the loads/stores after lowering, merging, and other relevant
  transformations.
- This patch adds 'MachhineModuleSlotTracker' to help assign slot
  numbers to these newly generated unnamed metadata nodes.
- To help 'MachhineModuleSlotTracker' track machine metadata, the
  original 'SlotTracker' is rebased from 'AbstractSlotTrackerStorage',
  which provides basic interfaces to create/retrive metadata slots. In
  addition, once LLVM IR is processsed, additional hooks are also
  introduced to help collect machine metadata and assign them slot
  numbers.
- Finally, if there is any such machine metadata, 'MIRPrinter' outputs
  an additional 'machineMetadataNodes' field containing all the
  definition of those nodes.

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.
