In VarDecl::getSourceRange() make sure to check that the source location 

of the initializer is valid before using it.

Fixes rdar://12455002&12449015 where local variables of objc objects in ARC mode
were not annotated because of the ImplicitValueInitExpr initializer having invalid
source range, resulting in the SourceRange of the VarDecl having invalid end location.
