Florian Hahn 076513646c [Local] Only intersect llvm.access.group metadata if instr moves. (#115868) ...

Preserve llvm.access.group metadata on the replacement instruction, if
it does not move. In that case, the program would be UB, if the parallel
property encoded in the metadata does not hold.

This matches the LangRef recently updated in #116220
