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

4b265c2ee3 Display quiet NaNs as 'NaN'. 
This is recommended by IEEE 754-2008.

We still distinguish signaling NaNs with 'sNaN'.

524eb77185 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.

ad07f67331 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.

a2db4b680e Move instruction definitions into meta. 
Use the meta language to define instructions, just insert 'autoinst' references
in langref.

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.
