Manman Ren 16649b0107 TBAA: remove !tbaa from testing cases if not used. 
This will make it easier to turn on struct-path aware TBAA since the metadata
format will change.

Jakob Stoklund Olesen 2e22e6a361 %RCX is not a function live-out in eh.return functions. 
The function live-out registers must be live at all function returns,
and %RCX is only used by eh.return. When a function also has a normal
return, only %RAX holds a return value.

This fixes PR13188.
