snippet that triggers the segfault

Segfaults when compiled with -O3 -mcpu=cell -mwarn-cell-microcode.

------- Comment #2 from pinskia at gcc dot gnu dot org  2010-04-16 00:52 -------
Confirmed.  The problem is from:
  /* Vector constant 0 is handled as a splitter of V2SI, and in the
     pattern of V1DI, V4HI, and V2SF.

     FIXME: We should probably return # and add post reload
     splitters for these, but this way is so easy ;-).  */
