3a72662d - Restructure comparison ops so as to better support XLA dispatch (#29591)

Restructure comparison ops so as to better support XLA dispatch (#29591) Summary: Per ailzhang's suggestion in https://github.com/pytorch/pytorch/pull/28162#discussion_r344361926, this PR changes the implementation of binary comparison and logical ops to those of unary ops in UnaryOps.cpp. The reason is that the call should eventually go through at::op_out (e.g., at::logical_xor_out). The check for Boolean output tensor is also removed, because: - This check should only apply to _out functions but not on other variants. However, other variants must go through the _out variant eventually. - It does not have a clear motivation and seems unnecessary.
