errs() is no good. I would want to keep errs() printing things out
immediately. I need something else that buffers until program termination.
So I would write the above as:
DEBUG(dbgs() << foo);
Does that sound reasonable?
There are some tricky cases where dump routines are used either to
print error messages or to print debug information. In those cases
I may have to parameterize the dump routine with the stream.
