Currently those operators are imported with a `consuming:` label, which isn't valid in Swift.
We could just remove the label from these parameters, but that introduces a source breakage due to name lookup ambiguity.
So, to avoid ambiguity, let's not import such operators into Swift.

(cherry picked from commit eb7adc794d)
This does not include subscript operators.
Before this is re-enabled operators need to be re-implemented. Right now they are the source of a lot of bugs. They cause frequent crashes and mis compiles. Also, templated operators insert a lot of names into global lookup which causes problems.
They also don't work on Windows.
