[Analysis] Add Intrinsics::CLMUL case to cost calculations to getIntrinsicInstrCost / getTypeBasedIntrinsicInstrCost (#176552)
This patch adds a case in getIntrinsicInstrCost and
getTypeBasedIntrinsicInstrCost in
llvm/include/llvm/CodeGen/BasicTTIImpl.h for Intrinsic::clmul. This
patch uses TLI->isOperationLegalOrCustom to check if the instruction is
cheap. If not cheap, it sums up the cost of the arithmetic operations
(AND, SHIFT, XOR) multiplied by the bit width.
Fixes #176354
