Serguei Katkov 09ab506798 [IR Verifier] Do not allow bitcast of pointer to vector of pointers and vice versa. ...

LangRef for BitCast requires that
"The bit sizes of value and the destination type, ty2, must be identical".
Currently verifier allows BitCast of pointer to vector of pointers so that
the sizes are different.

This change fixes that.
