Add legalizations for icmp and icmp_imm for i64 and i128 operands for the narrow legalization set, allowing 32-bit ISAs (like x86-32) to compare 64-bit integers and all ISAs to compare 128-bit integers. Fixes: https://github.com/bnjbvr/cranelift-x86/issues/2
This crate contains shared definitions for use in both cranelift-codegen-meta and cranelift -codegen.
