Not out of the box.
What you could do is compile your code several times with different 
options and make each version into a separate dll, then select the right 
dll to load at runtime.

Alternatively you could also compile the code at runtime.

We have things that can do that in the work for NT2 that we use for OpenCL.

Boost.SIMD does not have knowledge of high-level routines, and obviously 
you don't want to switch on each basic function...
