3ffeab7f - [custom_op] Make repeated registrations error gracefully (#100979)

[custom_op] Make repeated registrations error gracefully (#100979) Previously the error message went through torch.library. This PR changes it so that on each custom_op.impl_* call: - we store a (function, location) tuple - if a (function, location) tuple exists already, then we raise an error. This logic already existed for the abstract impl (the impl for meta and fake tensors), so this PR just extends it to the others. Test Plan: - new test Pull Request resolved: https://github.com/pytorch/pytorch/pull/100979 Approved by: https://github.com/bdhirsh, https://github.com/soulitzer
