llvm dev - Apr 2021 - Error due to TBAA access tag not created by me

Hello.
     I get a strange error when I create a shufflevector instruction with the
IRBuilder
with the following standard code:
	  ...
           Value *shuffleVec = Builder.CreateShuffleVector(
                              src, // The 1st source vector
                              UndefValue::get(VectorTy_1), // The 2nd source
vector - undef
                              ConstantVector::get(shuffleMask));

     The reason is that during code generation LLVM automatically adds by itself
(haven't
figured out where; I'm using LLVM version 9 from 2019) the TBAA attribute
(from Type-Based
Alias Analysis). And then, later, the LLVM verifier complains:
      <<This instruction shall not have a TBAA access tag!
        %5 = shufflevector <8 x i16> %4, <8 x i16> undef, <8 x
i32> <i32 2, i32 %3, i32 4,
i32 5, i32 6, i32 7, i32 0, i32 1>, !dbg !24, !tbaa !26>>
     and then opt (or llc) stops with error:
       <<LLVM ERROR: Broken function found, compilation aborted!>>

     So to be able to get rid of this TBAA tag I used:
           opt -disable-verify,
        and then I edited the .ll file generated and simply removed the TBAA
tag.

     Could you please tell me if there is an easier way to get rid of these TBAA
tags? For
example, can we simply avoid to create these tags in the first place?

   Thank you very much,
     Alex
