[Bug rtl-optimization/16104] [3.3/3.4 regression] ICE in reload_cse_simplify_operands, at postreload.c:378 with SSE2 code on -O2

this is small testcase for original bug (ICE in postreload.c),
it fails in 3.3 and 3.4 but not in 4.0.0, use -Os -msse2 to repeat:
-----------------------------------------------------------------------------------------
void foo (int *j)
{
  int __attribute__ ((mode (V2SI))) k;
  long long t = (long long) k;
  j[0] = t;
}
-----------------------------------------------------------------------------------------

Note I cannot repeat this bug on 4.0.0 neither with this nor with Volker's
testcases, so I cleared 4.0 regression flag.
