Reduce case iteration counts in SeekUnroll.

This test was taking too long to run on x86. After investigation, it
does not appear that there is a fundamental problem with the code
generated for the test; rather, it seems that we are running an
excessive number of iterations when using this test as a correctness
test. This change reduces the number of times we run each case from 10
to 1 unless otherwise specified on the command line.
