This harness is a highly-focused stress test of the prepare_*_call_frame functions. It uses the shared helpers to generate a pool of random infix_type objects within a single memory arena. It then constructs random function signatures from this pool and calls the ABI classification logic directly.

The test's only goal is to find inputs that cause crashes, hangs, or sanitizer errors within the ABI classifiers.
