Reviewed by Keith Miller.

This patch imports simd-everywhere[1]. This implements almost all of ARM64 NEON intriniscs
on any platforms so that we can just globally use ARM64 NEON SIMD. We enabled ARM64-exclusively written SIMD code for x64 too.
Right now, we are not enabling SIMD for x64 yet. We do that in a separate patch.
Note that Apple OSS approval ID is OSS-14094.
