      As discussed at https://github.com/openjdk/jdk/pull/28141/files#r2496215037, BootTest is used in a fragile way currently.

      It's worth to refactoring BootTest, e.g. encapsulate it; and `unsigned_compare` is not formally/well supported by BootTest, but it's used in both vector intrinsics and auto-vectorization, this is also worth of an investigation and refactoring.
