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.

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.

Some polymorphic instructions don't return the controlling type
variable, so it has to be computed from the designated operand instead.
- Add a requires_typevar_operand() method to the operand constraints
which indicates that.
- Add a ctrl_typevar(dfg) method to InstructionData which computes the
controlling type variable correctly, and returns VOID for monomorphic
instructions.
- Use ctrl_typevar(dfg) to drive the level-1 encoding table lookups.

When the liveness pass implements dead code elimination, missing live
ranges can be used to indicate unused values that it may be possible to
remove. But even then, we may have to keep dead defs around if the
instruction has side effects or other live defs.
