Summary: Use existing workaround for batched 3x3 symeig because it is faster than torch.symeig. Added benchmark showing speedup. True = workaround. ``` Benchmark Avg Time(μs) Peak Time(μs) Iterations -------------------------------------------------------------------------------- normals_True_3000 16237 17233 31 normals_True_6000 33028 33391 16 normals_False_3000 18623069 18623069 1 normals_False_6000 36535475 36535475 1 ``` Should help #988 Reviewed By: nikhilaravi Differential Revision: D33660585 fbshipit-source-id: d1162b277f5d61ed67e367057a61f25e03888dce
