In deference to Alexandre's desire to support CC0 here, I've reworked my 
patch for this.  It doesn't add the support for CC0 at this time, but does 
mean that doing so should be straight-forward.

I've taken the opportunity to rearrange the code slightly as well, so that 
we don't end up generating new RTL when we don't need it.

R.

	* flow.c (init_propagate_block_info): Don't abort if a conditional
	jump is not a comparison of a register.  Instead, just don't record
	conditional life information.
