Delete OperatorOptions, absorb AliasAnalysisKind into FunctionSchema. (#34160)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/34160
I constructed the patch by deleting OperatorOptions and then rerouting
all queries for AliasAnalysisKind to FunctionSchema. Some of the
behavior is kind of bogus: we really shouldn't be mutating FunctionSchema
after the fact, but that won't get fixed until we actually switch to
true schema merging.
