Revision 214080 causes an unrecognizable insn ICE when compiling the following
test case with -O2 -m32 -mlra:

[bergner@makalu-lp1 decnumber]$ cat testcase-min.i
typedef struct
{
  unsigned char bits;
} decNumber;

void
__decNumberPower (unsigned int status)
{
  int i;
  decNumber dacbuff;
  decNumber *dac = &dacbuff;
  for (i = 1;; i++)
    {
      if ((status & 0x2200) && (dac->bits & 0x70))
        break;
    }
  if (status & 0x2200)
    bar (dac);
}
