LOG: [ARM] Fold insert_subvector to concat_vectors
D107068 fixed the same problem on aarch64 but the arm variant wasn't exposed in existing test coverage.
I've copied the arm64-neon-copy tests (and stripped the intrinsic test from it) for testing on arm neon builds as well.
Added:
llvm/test/CodeGen/ARM/neon-copy.ll
Modified:
llvm/lib/Target/ARM/ARMISelLowering.cpp
