No objections from me.  The more verbose output is at the moment interesting
to me, but generally it hasn't been.  Having it selectable would IMHO
be a good thing.

BTW, can you throw your latest coalescing changes my way.  They're helpful
to work with when analyzing what's going on as they make the tree-ssa
output more closely resemble mainline in regards to how registers are
used.
