  Log Message:
  -----------
  Reapply "[X86] Limit X86InterleavedAccessGroup to handle the same type case only"

The current implementation assumes the destination type of shuffle is the same as the decomposed ones. Add the check to avoid crush when the condition is not satisfied.

This fixes PR37616.
