[PATCH][committed] aarch64: Add Linux kernel hwcap string for FEAT_CSSC

[Kyrylo Tkachov via Gcc-patches]

Hi all,

The Linux kernel has done basic enablement and detection of FEAT_CSSC so we can
use the cpuinfo string that they've specified.

This patchlet does that.

Bootstrapped and tested on aarch64-none-linux-gnu.
Pushing to trunk.
Thanks,
Kyrill

gcc/ChangeLog:

        * config/aarch64/aarch64-option-extensions.def (cssc): Specify
        FEATURE_STRING field.
