- Add TO_BOOL_GENERIC: a catch-all specialization for types not covered by existing TO_BOOL variants (dict, tuple, float, set, bytes, frozenset, etc. and heap types with __bool__/__len__). Records type info for the JIT. - Add _TO_BOOL_DICT: a tier2-only uop that checks dict.ma_used directly instead of calling PyObject_IsTrue(). The JIT optimizer replaces _TO_BOOL with _TO_BOOL_DICT when the type is known to be dict or frozendict. - Fix _GUARD_TYPE_VERSION optimizer handler to resolve types from recorded type info even when the type version cache has a collision. This enables the optimizer to eliminate redundant type guards (e.g. _GUARD_NOS_LIST) in more cases. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

We add
TO_BOOL_GENERICas suggested in #143732 (comment). This adds type information for several builtin classes. We also add_TO_BOOL_DICT(tier 2). In the jit conversion of a dict to bool is about 30% faster.
