The latest Sphinx 1.4.4 produces lots of warnings about four-column indices.
We'll wait for Read the Docs to upgrade their systems before moving to the newer
Sphinx version.

Naming is interesting here. Since 'truncate' refers to removing the least
significant digits, use 'ireduce' instead. The 'extend' use is fairly
established. Don't abbreviate, avoid unfortunate modern vernacular.

Move test-all.sh to the top level directory, and also run the parser tests from
this script.
Use a release build of cton-util to run the parser tests. As we accumulate many
tests in the tests directory tree, this will mean they can still be run quickly.
Point Travis config to the new test script.

This instruction uses two type variables: input and output. Make sure that our
parser can handle it. The output type variable annotation is mandatory.
Add a ValueTypeSet::example() method which is used to provide better diagnostics
for a missing type variable.

Add new intcc and floatcc operand types for the immediate condition codes on
these instructions.
Add new IntCompare and FloatCompare instruction formats.
Add a generic match_enum() parser function that can match any identifier-like
enumerated operand kind that implements FromStr.
Define the icmp and fcmp instructions in case.py. Include documentation for the
condition codes with these two instructions.

The icmp and fmp instructions use different kinds of condition codes because
integers and floating point values behave differently.
Add a CondCode trait implementing shared behavior.

These instruction formats take immediate lane index operands. We store these as
u8 fields and require them to be in decimal format in the source. No hexadecimal
lane indexes are supported.

Instructions that don't produce any result values are marked with first_type() =
VOID. The inst_results() iterator should not return any values for such
instructions.

The 'cton-util cat' command parses the given files and writes them out again to
stdout. This has the effect of reformatting and stripping comments.
Fix a writer bug that inverted the blank line before the first EBB.

Add an external dependency to the docopt package and use it for a scaffold
command line interface for the cton-util command.
I am not too happy about taking external dependencies, and docopt pulls in 13
other packages. However, I really don't want to be writing command line parsers,
and as long as the external dependencies are confined to the tools crate, we
should be fine.
The core cretonne crate should stay free of external dependencies to avoid
trouble with embedding it.
Implement a basic 'cat' subcommand which currently behaves like unix 'cat'. It
will gain parser powers soon.

Replace the make_multi_inst() function with a make_inst_results() which uses
the constraint system to create the result values. A typevar argument ensures
that this function does not infer anything from the instruction data arguments.
These arguments may not be valid during parsing.
Implement basic type inference in the parser. If the designated value operand
on a polymorphic instruction refers to a known value, use that to infer the
controlling type variable.
This simple method of type inference requires the operand value to be defined
above the use in the text. Since reordering the EBBs could place a dominating
EBB below the current one, this is a bit fragile. One possibility would be to
require the value is defined in the same EBB. In all other cases, the
controlling typevar should be explicit.
