[Dynamo] Fix guard bug when np.float used in control flow (#91991)
Fixes 14k github models: https://github.com/jansel/pytorch-jit-paritybench/blob/master/generated/test_Sanster_lama_cleaner.py#L2392

```np.float``` is unspecialized by default, which has guard on ```TYPE_MATCH```. However, it will be baked when being used in control flow, which has guard on ```EQUALS_MATCH```. We should make ```EQUALS_MATCH``` support ```np.float```.
