Trevor Elliott f5ad74e546 cranelift: Add narrower and wider constraints to the instruction DSL (#6013) ...

* Add narrower and wider constraints to the instruction DSL

* Add docs to narrower/wider operands

* Update cranelift/codegen/meta/src/cdsl/instructions.rs

Co-authored-by: Jamey Sharp <jamey@minilop.net>

* Fix assertion message

* Simplify upper bounds for the wider constraint

* Remove additional unnecessary cases in the verifier

* Remove unused variables

* Remove changes to is_ctrl_typevar_candidate

These changes were only necessary when the type returned by an
instruction was a variable constrained by narrow or widen. As we have
switched to requiring that constraints must appear on argument types and
not return types, these changes were not longer necessary.
