It turns out that Souper does not allow a constant to be assigned to a variable, they may only be used as operands. The 2.0.0 version of the `souper-ir` crate correctly reflects this. In the `cranelift_codegen::souper_harvest` module, we need to modify our Souper IR harvester so that it delays converting `iconst` and `bconst` into Souper IR until their values are used as operands. Finally, some unit tests in the `peepmatic-souper` crate need some small updates as well.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
