Use the DataLayout-aware TargetFolder instead of ConstantFolder in Clang's CGBuilder. The primary impact of this change is that GEP constant expressions are now emitted in canonical `getelementptr i8` form. This is in preparation for the migration to ptradd, which requires this form. Part of the test updates were performed by Claude Code and reviewed by me.
