  29 /* Generic helper functions for doing 128-bit SIMD arithmetic in cases
  30    where the instruction selectors cannot generate code in-line.
  31    These are purely back-end entities and cannot be seen/referenced
  32    as clean helper functions from IR.
  33
  34    These will get called from generated code and therefore should be
  35    well behaved -- no floating point or mmx insns, just straight
  36    integer code.
  37
  38    Each function implements the correspondingly-named IR primop.
