Performance regression in v0.50.0 #2756

[Test]
[MethodDataSource(nameof(Ints))]
public async Task Test1(int i)
{
await Assert.That(i).IsGreaterThan(0);
}
public static IEnumerable<int> Ints() => Enumerable.Range(1, 10000);
}Build with dotnet publish --use-current-runtime and then run the output executable.
In v0.25.21 the test duration was about 190ms, in v0.50.0 it takes about 350ms.
I also get performance differences without AOT, but using it makes it more noticeable.
