Pull Request Overview
This PR modifies the nullness analysis in C# to allow nullness sources with SSA (Static Single Assignment) at entry. The change removes a constraint that was excluding SSA entry definitions (which don't have an associated AST element) from being considered as potential null sources.
- Removes a
strictcountcondition that filtered out SSA definitions without AST elements - Enables detection of additional true positive null-related issues

Now that splitting is reduced, this particular condition only serves to rule out SSA entry definitions, since they don't have an associated AST element, and I don't think those sources should be excluded.
Looking through some of the dca result diffs all of the new results look like TPs to me.
