DMD doesn't support non-x86 platforms... What DMD offer's is fine, since it
all needs to be collated anyway; GDC/LDC don't agree on intrinsics either.
I already support ARM and did some PPC experiments in std.simd. I just use
the intrinsics that gdc/ldc provide, that's perfectly fine.

As said in my prior post, I think std.simd.sse, std.simd.neon, and friends,
might all be a valuable addition. But we'll need to see about the codegen
after it unravels a bunch of wrappers...
