Karl-Johan Karlsson 6d52e5c3e4 [ConstantFold] Disallow folding vector geps into bitcasts 
Summary:
Getelementptr returns a vector of pointers, instead of a single address,
when one or more of its arguments is a vector. In such case it is not
possible to simplify the expression by inserting a bitcast of operand(0)
into the destination type, as it will create a bitcast between different
sizes.
