arm: Enables return address verification and branch target identification on Cortex-M | expand

Message

Hi all,

this series enables return address verification and branch target
identification based on Armv8.1-M Pointer Authentication and Branch
Target Identification Extension [1] for Arm Cortex-M.

This feature is controlled by the newly introduced '-mbranch-protection'
option, contextually the Armv8.1-M Mainline target feature '+pacbti' is
added.

Best Regards

  Andrea
