  [X86] Improve demanded bits for X86ISD::BEXTR.

If the control is constant we can figure out exactly which bits
of the input are demanded.

  Log Message:
  -----------
  [SLP] Make HorizontalReduction::getOperationData take an Instruction* instead of a Value*. NFCI

All of the callers already have an Instruction *. Many of them
from a dyn_cast.

Also update the OperationData constructor to use a Instruction&
to remove a dyn_cast and make it clear that the pointer is non-null.
