Simplify parser.
Use 'if let' instead of 'match' where it makes sense.
Use EBNF notation for the grammar rules. This simplifies repetition a lot.

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.

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

Display quiet NaNs as 'NaN'.
This is recommended by IEEE 754-2008.
We still distinguish signaling NaNs with 'sNaN'.

Implement IEEE immediates for binary32 and binary64.
Clarify the textual encoding of floating point numbers.
Don't allow decimal floating point since conversion to/from binary can produce
rounding problems on some (buggy) systems.

Move constant instructions into meta.
Add new immediate types for floating point and vector immediates.
Use new immediates to define the constant value instructions in meta.
Split the fconst instruction into two: f32const and f64const. This prevents
confusion about the interpretation of 64 immediate bits when generating an f32
constant.
Add an immvector ImmediateType. This immediate type is variable length, and
provides all the bits of a SIMD vector directly.

generates documentation for one of the types in the cretonne.types module.

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.
