   What do you think would be the proper way to detect the cpu

Maybe there should be some kind of call, like
jit_get_cpu_features(), that one should call before generating
code, so that the macros jit_sse_p(), jit_i686_p(), etc,
could actually be runtime flags. Also, it may be desirable
to allow changing these flags, mainly for testing purposes.

Looks like a good idea.  I still haven't reviewed the branch though.
