Stephen Neuendorffer b0dce6b37f Revert "[RFC] Factor out repetitive cmake patterns for llvm-style projects"
This reverts commit e9b87f43bd.

There are issues with macros generating macros without an obvious simple fix
so I'm going to revert this and try something different.

Stephen Neuendorffer e9b87f43bd [RFC] Factor out repetitive cmake patterns for llvm-style projects
New projects (particularly out of tree) have a tendency to hijack the existing
llvm configuration options and build targets (add_llvm_library,
add_llvm_tool).  This can lead to some confusion.

1) When querying a configuration variable, do we care about how LLVM was
configured, or how these options were configured for the out of tree project?
2) LLVM has lots of defaults, which are easy to miss
(e.g. LLVM_BUILD_TOOLS=ON).  These options all need to be duplicated in the
CMakeLists.txt for the project.

In addition, with LLVM Incubators coming online, we need better ways for these
incubators to do things the "LLVM way" without alot of futzing.  Ideally, this
would happen in a way that eases importing into the LLVM monorepo when
projects mature.

This patch creates some generic infrastructure in llvm/cmake/modules and
refactors MLIR to use this infrastructure.  This should expand to include
add_xxx_library, which is by far the most complicated bit of building a
project correctly, since it has to deal with lots of shared library
configuration bits.  (MLIR currently hijacks the LLVM infrastructure for
building libMLIR.so, so this needs to get refactored anyway.)

River Riddle 6b4e30b7c8 Add Ch-7 of the toy tutorial detailing how to define new types.
This chapter adds a new composite type to Toy, and shows the process of adding a new type to the IR, adding and updating operations to use it, and constant folding operations producing it.

River Riddle 0372eb413f Add Ch.6 of the Toy tutorial.
This chapters introduces the notion of a full conversion, and adds support for lowering down to the LLVM dialect, LLVM IR, and thus code generation.

This introduces a basic MLIRGen through straight AST traversal,
    without dialect registration at this point.
