Switch to stable SIMD intrinsics.

Browse Source 
Rust 1.27 stablized a variety of cpu intrinsics, including SIMD
on x86/64 platforms.  This commit moves to using those intrinsics
for the optimized Float4 implementation.  This means Psychopath
now compiles on stable Rust with all optimizations.  Yay!
