Function run 

pub fn run<A, F, H>(
    factory: F,
    target: &TargetDescription,
    hooks: &H,
) -> ConformanceReport
where
    A: Accelerator,
    F: Fn() -> A,
    H: ConformanceHooks<A>,

Run every mandatory and advertised capability-conditional semantic case.

factory is called once per case so an indeterminate result or accounting contradiction can never contaminate a later case. The returned report preserves skips and all failures instead of stopping at the first defect.
