<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-backend-aarch64 Author: Martin Wehking (MartinWehking) <details> <summary>Changes</summary> Add a new __ARM_FEATURE_CSSC macro that can be utilized during the preprocessing stage. __ARM_FEATURE_CSSC is defined to 1 if there is hardware support for CSSC.
