LOG: [VPlan] Remove dead member functions (NFC) (#208936)

Remove member functions with no remaining callers anywhere in the tree:

 - VPExpressionRecipe::getOperandOfResultType
- VPBlockBase::getSingleHierarchicalSuccessor
 - VPIRFlags::hasNonNegFlag
- VPWidenIntOrFpInductionRecipe::getStartValue, which is an exact
duplicate of the inherited VPWidenInductionRecipe::getStartValue.

Added: 
    

Modified: 
    llvm/lib/Transforms/Vectorize/VPlan.h

Removed:
