BTW compile with -ftree-vectorizer-verbose=7 to check what gcc does.

If you're looking for something ready-made, there are SSE, and altivec
asm routines for mixing buffers and calculating the peak value in
ardour. Have a look at libs/ardour/*.s, libs/ardour/mix.cc and
libs/ardour/ardour/mix.h

GPL and everything, thanks to Sampo IIRC.
