593b7bbd51 Generate an InstructionFormat enum. 
This is a no-payload enum which will have the same variants as InstructionData.
This makes it possible to talk about the format of an instruction without
actually creating an InstructionData instance.

477fa01bfc Add OperandKind to the meta language. 
We have a two-level type system: OperandKinds and ValueTypes. The value types
only apply to value operands, but there are many more kinds of operands:
immediate numbers, condition codes, basic block references, etc.

6e2e7bfb73 Add a RISC-V target. 
Flesh out the directory structure for defining target instruction set
architectures. Use RISC-V as a startgin point because it is so simple.

5388f68437 Give instructions a CamelCase name. 
This will be used as the instruction name in Rust code. By making this a
property of the instruction, it can be changed by the user if desired.

f72f47aece Replace bool with b1, b8, b16, ... 
The b1 type is an abstract boolean value. The others are concrete
representations.

19b4facbe0 Add a TypeDocumenter for Cretonne types. 
Use the autodoc Sphinx module to add a .. autoctontype:: directive which
generates documentation for one of the types in the cretonne.types module.

c459c11a5a Begin defining the meta language. 
The Cretonne meta language is used to describe Cretonne instructions, both the
target independent ones in the base instruction set and real target
instructions.

Start by providing type definitions matching langref, and begin the meta
language reference using autodoc to pull in the PYthon definitions.
