With the Return and ReturnReg formats converted to using value lists for
storing their arguments, thee are no remaining instruction formats with
variable argument lists in boxed storage.
The Return and ReturnReg formats are also going to be merged since
they are identical now.
The Branch format also stores its fixed argument in the value list. This
requires the value pool to be passed to a few more functions.
Note that this actually makes the Branch and Jump variants of
InstructionData identical. The instruction format hashing does not yet
understand that all value operands are stored in the value list. We'll
fix that in a later patch.
Also convert IndirectCall, noting that Call and IndirectCall remain
separate instruction formats because they have different immediate
fields.

Add a new kind of instruction format that keeps all of its value
arguments in a value list. These value lists are all allocated out of
the dfg.value_lists memory pool.
Instruction formats with the value_list property set store *all* of
their value arguments in a single value list. There is no distinction
between fixed arguments and variable arguments.
Change the Call instruction format to use the value list representation
for its arguments.
This change is only the beginning. The intent is to eliminate the
boxed_storage instruction formats completely. Value lists use less
memory, and when the transition is complete, InstructionData will have a
trivial Drop implementation.

Read the Docs is now using the latest version of Sphinx, so upgrade our
recommended version too.
As of Sphinx 1.4, index entries are 5-tuples instead of 4-tuples. Update
the Cretonne Sphinx domain to generate the new 5-tuples.
Since we're over this compatibility bump, there's no reason to recommend
a specific Sphinx version, so just go back to 'current'.

If func.locations has not been properly resized to have an entry for all
values, we should just full in the default location for the missing
values instead of crashing.

Add a Function::display() method which can include ISA-specific
information when printing the function.
If a test file has a unique ISA, use that in the `test cat`
implementation.

Add support for two new type variable functions: half_vector() and
double_vector().
Use these two instructions to break down unsupported SIMD types and
build them up again.

Insert conversion code that reconstructs the original function argument
types from the legalized ABI signature.
Add abi::legalize_abi_value(). This function is used when adapting code
to a legalized function signature.

These two methods can be use to rewrite the argument values to an EBB.
In particular, we need to rewrite the arguments to the entry block to be
compatible with a legalized function signature.
Reuse the put_ebb_arg() method in the implementation of
append_ebb_arg().

Add an abi module with code that is probably useful to all ISAs when
implementing this function.
Add a unit() method to RegClassData which can be used to index the
register units in a class.

This entry point will be used for controlling ABI conventions when
legalizing.
Provide an empty implementation for RISC-V and let the other ISAs crash
in legalization.
This is just the scaffolding. We still need to:
- Rewrite the entry block arguments to match the legalized signature.
- Rewrite call and return instructions.
- Implement the legalize_signature() function for all ISAs.
- Add shared generic types to help with the legalize_signature()
functions.

The List and Dict types are no longer implicitly available. They must be
imported from typing.
Type annotations must appear before the doc comment in a function. Also
fix type errors in these functions that weren't detected before.

Rust 1.12 did work at one point, but Travis is testing against the
current stable and beta releases, so that is the only versions we can
claim to support.
Fixes#51.
