Arnold Schwaighofer df6f67ed87 LoopVectorizer: Pass OperandValueKind information to the cost model 
Pass down the fact that an operand is going to be a vector of constants.

This should bring the performance of MultiSource/Benchmarks/PAQ8p/paq8p on x86
back. It had degraded to scalar performance due to my pervious shift cost change
that made all shifts expensive on x86.
