[PATCH] D30469: [PowerPC] Expand compare instructions to equivalent GPR code sequences.

Comparison is often used with bit operators, like an example below.
In this example, as long as I test, the transformation is applied only when POS is 0; compd + isel are used for cases with POS > 0.
I feel it is nice if we can support comparisons used with bit operators.

  const int POS = 1;
  long set_flag(long a, long b, long flags) {
  	flags |= ((a == b) << POS);
  	return flags;
  }
