This commit disables the `MachBuffer::check_label_branch_invariants` debug check on the fuzzers due to it causing timeouts with the test case from #3441. Fuzzing leads to a 20-30x slowdown of executed code and locally the fuzz time it takes to instantiate #3441 drops from 3 minutes to 6 seconds disabling this function. Note that this should still be executed during our testing on CI since it's still enabled for debug assertions.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
