8b484b1c77 Binary function names (#91)
* Function names should start with %

* Create FunctionName from string

* Implement displaying of FunctionName as %nnnn with fallback to #xxxx

* Run rustfmt and fix FunctionName::with_string in parser

* Implement FunctionName::new as a generic function

* Binary function names should start with #

* Implement NameRepr for function name

* Fix examples in docs to reflect that function names start with %

* Rebase and fix filecheck tests

832247019b Remove the return_reg instruction.
RISC architectures that take a return address in a register can use a
special-purpose `link` return value to do so.

23ae70cacf Flatten the Value reference representation.
All values are now references into the value table, so drop the
distinction between direct and table values. Direct values don't exist
any more.

Also remove the parser support for the 'vxNN' syntax. Only 'vNN' values
can be parsed now.

e4a83c8063 Break out differently purposed tests from abi.cton.
- abi.cton is for testing the actual RISC-V ABI.
- legalize-abi.cton is for testing the legalizer around ABI boundaries.
- parse-encoding.cton is for testing the parser's handling of RISC-V
  encoding and register annotations.

28153c97ea Legalize ABI arguments to call and return instructions.
The type signatures of functions can change when they are legalized for
a specific ABI. This means that all call and return instructions need to
be rewritten to use the correct arguments.

- Fix arguments to call instructions.
- Fix arguments to return instructions.

TBD:

- Fix return values from call instructions.

83d3a1020d 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.

25677d1bd8 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.

5d266acb5f 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.

e84a4e41a0 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.
