New Revision: 153714

URL: http://llvm.org/viewvc/llvm-project?rev=153714&view=rev
Log:
Change location information for synthesized properties to be at the
property file/line rather than the @synthesize file/line. Avoids
some nasty confusing-ness with conflating the file from the scope
and the line from the original declaration.

Update a couple of testcases accordingly since I had to change
that we actually use the passed in location in EmitFunctionStart.

Fixes rdar://11026482
