cb3e503f07 Use ISA information to display function signatures. 
The argument locations contains register unit references that we want to
display with their correct names.

99c7e18fbf Add {ValueLoc,ArgumentLoc}::display(). 
These functions return an object containing the necessary ISA info to
print a ValueLoc or ArgumentLoc correctly.

c01ff670ed Fixed for mypy 0.501. 
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.

1f76521580 Require a current Rust version. 
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.

cf5701b137 Add ABI annotations to function signatures. 
Specify the location of arguments as well as the size of stack argument
array needed. The ABI annotations are optional, just like the value
locations.

Remove the Eq implementation for Signature which was only used by a
single parser test.

247be57042 Also write out register assignments in write_instruction. 
The value locations appear after the encodings:

> [Iret#19]               return_reg v0

8e421d666d SSA register coloring pass. 
This is a bare-bones outline of the SSA coloring pass. Many features are
missing, including:

- Handling instruction operand constraints beyond simple register
  classes.
- Handling ABI requirements for function arguments and return values.
- Generating shuffle code for EBB arguments.
