HEAD is now at 2031ff16 Slight pivot: postpone shape handling enhancements till after achieving performance
HEAD is now at 45cd1e09 Introduce a new IR variant: `Constant_bits` for int64 constants, by Claude Claude found out that the discrepancy between sync_cc and metal backends was due to metal casting a float-single to uint4x32, while pure C was casting a double. This should go away with using Constant_bits / Tensor.bits for Fetch Embed_self_id and Tensor.get_random_seed
