optimization/10315: [3.2/3.3 regression] [powerpc] ICE: in extract_insn, at recog.c:2175

[David Edelsohn]

	The problem is easy_fp_constant():

  /* If we are using V.4 style PIC, consider all constants to be hard.  */
  if (flag_pic && DEFAULT_ABI == ABI_V4)
    return 0;

This means that "input_operand" predicate fails for movdf_hardfloat32 when
presented with const_double:DF.  I'm not sure what's suppose to save us at
that point.
