Symbolic Swift breakpoints should map back to Objective-C implementation

Classification:UI/Usability Reproducible:Always
 
Summary:
If a symbolic breakpoint is attempted to be set using Swift syntax, then it should match implementations that are known to originate in Objective-C.

For example if I set a breakpoint in lldb for "UIView.layoutSubviews" then lldb should be aware on behalf of Swift developers, that this is an automatic mapping from the Objective-C -[UIView layoutSubviews] and set the breakpoint on the pertinent lower-level symbol.

By choosing to expose system level frameworks to Swift developers with a modified syntax, it seems Apple should take on the burden of making sure that modified syntax is treated as canonical regardless of the implementation language.
