Add SIMD about mathgl HOT 7 OPEN

Would this break GopherJS compatibility?

I'm starting to rely on mathgl as my vector library when developing using WebGL, so it'd be really nice to be able to continue to do that.

Currently:

mgl32 $ go test
PASS
ok      github.com/go-gl/mathgl/mgl32   0.009s
mgl32 $ gopherjs test
ok      _/Users/Dmitri/Dropbox/Work/2013/GoLand/src/github.com/go-gl/mathgl/mgl32   0.222s

from mathgl.

I'll definitely add either a buildtag or an extra make command that does
everything without the SIMD stuff. I'm not sure which would be more
convenient.

Off topic: Woah @ GopherJS

Other note: apparently SIMD for a Mat3 determinant is also not worth it, though this is because of the necessary passthrough to another function (you can't define assembly on a pointer receiver).

Auto-vectorization in the compiler would be the ultimate ideal, but one could also make a code generation tool to vectorize your math heavy functions into assembly routines.

Edit: This would be a tool for the mathgl user, to vectorize entire algorithms. Not for vectorizing each individual Mat4 routine, etc.

@Jragonmiris can you post your SIMD code ?

from mathgl.

Let me see if I can dig it up
