David Green 6fb93f326d [UnJ] Improve explicit loop count checks ...

Try to improve the computed counts when it has been explicitly set by a pragma
or command line option. This moves the code around, so that first call to
computeUnrollCount to get a sensible count and override that if explicit unroll
and jam counts are specified.

Also added some extra debug messages for when unroll and jamming is disabled.
