eebc390e - [DA] Fix overflows when calculating Delta in the Weak Zero SIV tests (#184997)

[DA] Fix overflows when calculating Delta in the Weak Zero SIV tests (#184997) Add overflow checks when computing `Delta` in the Weak Zero SIV tests. The tests bail out if we cannot prove that the `Delta` computation does not overflow. These calculations are also moved later so that some analyses that do not require these checks can run first. Fix part of the test cases added in #164246.
