Fix generic code emission when building with LLVM3.0/2.9.

Browse Source 
Specifically, don't use vector select for masked store blend there,
but emit a call to a undefined __masked_store_blend_*() functions.

Added implementations of these functions to the sse4.h and generic-16.h
in examples/instrinsics.  (Calls to these will never be generated with
LLVM 3.1).
