Tejas Joshi 0609b65aaf [SCEV] Fix potentially empty set for unsigned ranges ...

The following commit enabled the analysis of ranges for heap allocations:
22ca38da25

The range turns out to be empty in cases such as the one in test (which
is [1,1)), leading to an assertion failure. This patch fixes for the
same case.
