[LLVMbugs] BitSetVector::iterator

[Casey Carter]

BitSetVector::iterator uses a BitSetVector& to track the BSV into which 
it is pointing: this is all fine and dandy, except that its operator= 
assigns the reference member.  If you want to be able to change it, use 
a pointer instead.

One of the BitSetVector::iterator constructors takes a BitSetVector by 
value instead of reference, and holds a reference to the argument.
