  [X86] Remove dyn_casts to ConstantSDNode for operand 1 of X86ISD::VSRLI/VSRAI/VSRLI. Use getConstantOperandVal and APInt operations.

These nodes should only ever be formed with an i8 TargetConstant
so we don't need to check for it to be a constant. It's also
always 8-bits so we don't need to use APInt compare functions.

  Log Message:
  -----------
  [X86] Use APInt::isOneValue and ConstantSDNode::isOne. NFC

These are implemented slightly more efficiently than comparing
to 1 in the case that the value is more than 64 bits.
