Shard Operators.cpp (#62185)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/62185
This file can take 5 minutes on its own to compile, and is the single limiting
factor for compile time of `libtorch_cpu` on a 32-core threadripper. Instead,
sharding into 5 files that take around 1 minute each cuts a full minute off the
overall build time.
This also factors out the `.findSchemaOrThrow(...).typed` step so the code can
be shared between `call` and `redispatch`.
