In cases where this causes TPU tests to fail, relax test tolerances in the test cases themselves.
TPUs are less precise only for specific operations, notably matrix multiplication (for which usually enabling higher-precision matrix multiplication is the right choice if precision is needed), and certain special functions (e.g., log/exp/pow).
The net effect of this change is mostly to tighten up many test tolerances on TPU.
