Philip Reames 46bf481c61 [IndVars] Fix a bug noticed by inspection
We were computing the loop exit value, but not ensuring the addrec belonged to the loop whose exit value we were computing.  I couldn't actually trip this; the test case shows the basic setup which *might* trip this, but none of the variations I've tried actually do.
