40fc5da3d8 Heed uext and sext annotations on RISC-V arguments.
Translate the small integer arguments to i32 or i64 with the appropriate
extend and ireduce instructions.

fd58b7cc29 Add vsplit and vconcat instructions.
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.

37b2e94c72 Legalize entry block arguments to match ABI types.
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.

77492aa463 Add take_ebb_args(), put_ebb_arg() method pair.
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().

42e7021865 Implement legalize_signature for RISC-V.
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.

07f459fb93 Add a legalize_signature method to TargetIsa.
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.

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.
