Instead, when the `rebuild-peephole-optimizers` feature is enabled, rebuild them the first time they are used. This allows peepmatic to run when Cranelift's `Opcode` is defined and available, which paves the way forward for: * merging `peepmatic_runtime::operator::Operator` and Cranelift's `Opcode` (we are wasting a bunch of cycles converting between the two of them), and * supporting vcode optimizations in `peepmatic`.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
