Summary: There's an asymmetry in the definitions of findBaseDefiningValueOfVector() and findBaseDefiningValue() of RS4GC. The later handles call and invoke instructions, and the former does not. This appears to be simple oversight. This patch remedies the oversight by adding the call and invoke cases to findBaseDefiningValueOfVector().
