Memory tagging is used for detecting memory safety bugs. On AArch64, the
memory tagging extension (MTE) helps in reducing the overheads of memory
tagging:
- CPU: MTE instructions for efficiently tagging and untagging memory.
- Memory: New memory type, Normal Tagged

addition between two tags.
The default of this hook is to byte add the inputs.

Hi,
Please find a new series of patches that implememnts stack sanitizer

What is new:
- Introduces a new target instruction tag_memory.
- Introduces a new target hook to deal with
