[SCEV] Remove a test case added in r249168

Browse Source 
The test case wasn't testing what it was commented to be testing; and
when I tried to fix the test I noticed that SCEV does not support the
simplification that the test was supposed to test.

This change removes the test case to avoid confusion.
