[clang-tidy] Add "portability" module and rename readability-simd-intrinsics to portability-simd-intrinsics Reviewers: alexfh Subscribers: klimek, nemanjai, mgorny, xazax.hun, kbarton, cfe-commits Differential Revision: https://reviews.llvm.org/D44173 llvm-svn: 326909

[clang-tidy] Add `readability-simd-intrinsics` check. Summary: Many architectures provide SIMD operations (e.g. x86 SSE/AVX, Power AltiVec/VSX, ARM NEON). It is common that SIMD code implementing the same algorithm, is written in multiple target-dispatching pieces to optimize for different architectures or micro-architectures. The C++ standard proposal P0214 and its extensions cover many common SIMD operations. By migrating from target-dependent intrinsics to P0214 operations, the SIMD code can be simplified and pieces for different targets can be unified. Refer to http://wg21.link/p0214 for introduction and motivation for the data-parallel standard library.
