Bug/issue #, if applicable: rdar://130750134

Summary

This fixes a bug where parameter and return value documentation wasn't hidden from language representations of a symbol without a function signature (for example properties).

With these changes, if one of the symbol's language representation has a function signature, all property and return value documentation will be hidden from its language representations that don't have function signatures.

Dependencies

None

Testing

• In a mixed Swift and Objective-C project, add a symbol that's a function in C but refines to a property in Swift. For example

  typedef struct {
      CGPoint center;
      CGFloat radius;
  } TLACircle NS_SWIFT_NAME(Circle);
  
  /// Returns whether a circle has zero radius.
  /// - Parameter circle: The circle to examine.
  /// - Returns: `YES` if the specified circle is empty; otherwise, `NO`.
  BOOL TLACircleIsEmpty(TLACircle circle) NS_SWIFT_NAME(getter:Circle.isEmpty(self:));

• Build documentation for the project and view the isEmpty Swift property documentation.

  • The Swift language representation shouldn't display a parameters or return value section.
  • The C/Objective-C language representation should display both a parameters or return value section.
