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