The x64 lowring of `vany_true` both sinks mergeable loads and uses the original register. This PR fixes the lowering to force the value into a register first. Ideally we should solve the issue by catching this in the ISLE type system, as described in #4745, but this resolves the issue for now. Fixes #4807.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
