[TensorExpr] Don't rely on exceptions in Vectorizer. (#64609)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/64609
We've been using exceptions to indicate whether vectorization succeeded
or not, but that posed some problems with (e.g. we spent too much time
symbolicazing these exceptions). This change converts this mechanism to
a standard error return code.
