  Log Message:
  -----------
  [AArch64] Guard {vmull_p64, vmull_high_p64} with 'aes' target guard.

The 'aes' target guard includes both FEAT_AES and FEAT_PMULL currently.

In this way, cpp code that uses these intrinsics without specifying the required extension gets better hint.
- Before, compile crashes with LLVM ISel internal message (see issue [[ https://github.com/llvm/llvm-project/issues/59599 | 59599 ]]).
- After, clang hints that target 'aes' is required in the command.
