[ODE] SIMD ODE code?

[Rodrigo Hernandez]

There is none that I know off, at least not an official one yet.

dVector3 is defined as float[4], and I added the "--with-arch=" 
parameter to configure in prevision for SIMD optimization, but
nothing more is there.

a good starting point towards SIMD integration would be modifying the 
macros in odemath.h to use SIMD intrinsic functions or inline asm and
defining dVector3 and dVector4 as __attribute__ ((aligned (16))).

Also, what flags are you using? in for a Pentium 4 you'd want to use 
-march=pentium4 |-mfpmat=sse and maybe throw in -malign-double.
