New Revision: 318724

URL: http://llvm.org/viewvc/llvm-project?rev=318724&view=rev
Log:
Add default values for member functions.

Initialize IsVis2 and IsVis3 in SparcSubtarget::initializeSubtargetDependencies.
MSan detected uninitialized read of IsVis3 after r318704.  Initializing the
variables to false will prevent undefined behavior.
