Implemented `Umulhi` for the Cranelift interpreter, performing unsigned integer multiplication and producing the high half of a double-length result. Fixed `ExtractUpper` conversion behaviour as part of this change, which was extracting from a 128-bit value regardless of the size of the original value. Copyright (c) 2021, Arm Limited.
This crate provides an interpreter for Cranelift IR. It is still a work in progress, as many instructions are unimplemented and various implementation gaps exist. Use at your own risk.
