    A llvm/test/Transforms/EarlyCSE/AArch64/intrinsics-1xN.ll

  Log Message:
  -----------
  [AArch64][TTI][EarlyCSE] Add support for ld1xN and st1xN intrinsics (#198765)

Handle ld1x2, ld1x3, ld1x4, st1x2, st1x3, st1x4 in:
- AArch64TTIImpl::getTgtMemIntrinsic
- AArch64TTIImpl::getOrCreateResultFromMemIntrinsic

This enables EarlyCSE to optimize these NEON load/store intrinsics.

To test the changes, a new testcase (intrinsics-1xN.ll) derived from
llvm/test/Transforms/EarlyCSE/AArch64/intrinsics.ll is added.
