@huntergr @dmgreen Thanks for your reviews.

I added tests to `clang/test/Driver/aarch64-cpus.c` and `clang/test/Preprocessor/aarch64-target-features.c`.

Yes, you are correct. 'Dot product' in Fujitsu techincal papers denotes 'integer dot product' in SVE, not 'SIMD dot product' in ARMv8.2-DotProd.

My colleague measured SPEC CPU2017 with PrefLoopLogAlignment = 2 and 5. The performance effect varies depending on benchmarks, and we could determine the best parameter. I want to submit this patch with 5 and revisit it later (possibly with the scheduling model).
