Fix formatting over overloaded operators.

This fixes llvm.org/pr14686.

We used to add too many spaces for different versions of overloaded operator
function declarations/definitions. This patch changes, e.g.

  operator *() {}
  operator >() {}
  operator () () {}

to

  operator*() {}
  operator>() {}
  operator()() {}
