/* Generic helper functions for doing 128-bit SIMD arithmetic in cases
   where the instruction selectors cannot generate code in-line.
   These are purely back-end entities and cannot be seen/referenced
   as clean helper functions from IR.

   These will get called from generated code and therefore should be
   well behaved -- no floating point or mmx insns, just straight
   integer code.

   Each function implements the correspondingly-named IR primop.
