Hi,

This patch adds the -march feature +pacbti to Armv8.1-M Mainline.
This feature enables pointer signing and authentication instructions
on M-class architectures.

Tested on arm-none-eabi. OK for trunk?

gcc/Changelog:

        * config/arm/arm-cpus.in: Define new feature pacbti.
        * config/arm/arm.h (TARGET_HAVE_PACBTI): New.

"+pacbti" needs to be documented in invoke.texi at the appropriate place.
