Would it be possible to save the reduced testcase somewhere?  It's nice not
to have to sift through a whole application.  If the application starts 
failing, it would be convenient to run the smaller testcases to see if 
there's been a regression.

Perhaps we need a second-tier "make check" for larger testcases that only
gets run once a week or maybe just when llvm-test fails.  Would that be
helpful?
