2dc15b78ae Add restrictions on polymorphism.
Also introduce the concept of a derived type variable, and provide two
methods for deriving type vars: lane() and as_bool().

bd221af412 Reorganize meta language reference.
Separate instruction descriptions from instruction formats which deal with the
Rust representation.

Add type class restrictions to type variables.

3670f57c40 Synchronize InstructionFormat and InstructionData.
These two enums must have identical variants. One is generated from the
instruction formats in meta/cretonne/formats.py, the other defines the contents
of an instruction.

Emit a conversion from InstructionData to InstructionFormat which also serves
to verify the correspondence. Rustc will error is the match is not complete.

e3927e205e 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.

814231245c 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.

7bf4570ba1 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.

936d6e523a 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.

043bb1aba5 Replace bool with b1, b8, b16, ...
The b1 type is an abstract boolean value. The others are concrete
representations.

06f9b65e12 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.

ec918fe332 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.
