Henrik RydgårdandClaude Opus 5.5 cdf238db7c Unit tests: Add CPUEquivalence, a differential fuzzer for the CPU cores

Runs random straight-line ALU, FPU, VFPU and load/store code from a
random state on every core and compares the full end state against the
interpreter, NaN payloads aside. Differing cases are minimized and
printed with their inputs. Options (seed, count, instruction classes,
code override, state dump for comparing hosts) are environment
variables, and Tools/cpu_fuzz_reduce.py finds and reduces a crashing
case. Known differences remain, so only a crash fails it by default.

What it found, and what's still open: docs/cpu-equivalence.md.
