[Local] Only intersect tbaa metadata if instr moves. (#116682)
Preserve tbaa metadata on the replacement instruction, if it does not
move. In that case, the program would be UB, if the aliasing property
encoded in the metadata does not hold.
This makes use of the clarification re tbaa metadata implying UB if the
property does not hold: https://github.com/llvm/llvm-project/pull/116220
Same as https://github.com/llvm/llvm-project/pull/115868, but for !tbaa
