  Log Message:
  -----------
  [Asan] Provide TTI hook to provide memory reference infromation of target intrinsics. (#97070)

Previously asan considers target intrinsics as black boxes, so asan
could not instrument accurate check. This patch provide TTI hooks to
make targets describe their intrinsic informations to asan.

Note,
1. this patch renames InterestingMemoryOperand to MemoryRefInfo.
2. this patch does not support RVV indexed/segment load/store.
