<pre>It seems that clobbering a non-allocatable register that aliases an allocatable
one is not really supported (I vaguely recall Andy and/or Jakob pointing this
out to me a long time ago in the context of the ctr-based loops design
discussion), so I implemented the 'cc' alias for 'cr0' directly within the
inline asm constraint-processing code. In short, r223708 should fix this.</pre>
