PR tree-optimization/52904 testcase


Hi,

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52904

Tescase was generating warning: assuming signed overflow does not occur
when simplifying conditional to constant [-Wstrict-overflow] due to VRP
missing the value range.

This seems to have been fixed and the PR is now closed. However, as
requested there in the PR, I am sending this patch to add the test-case
to test-suite.


Is this OK ?

Thanks,
Kugan
