  -----------
  [RISCV] Stop ignoring intrinsics in costing for force unrolling (#221107)

All intrinsic calls were hitting the "continue" for !isLoweredToCall
and bypassing the getInstructionCost.

I've modified runtime-unroll-max-trip-count.ll to override unrolling
costs and remove the bswap intrinsics that were previously not counted.

Test case written by Claude.
