Allow users to set gcAllowVeryLargeObjects for Runtime Settings

[AndreyAkinshin]

See MSDN page: Runtime Settings Schema
We can implement some logic that will specify some parameters (e.g. gcAllowVeryLargeObjects, gcConcurrent, gcServer look useful). We can define default values and allow to specify custom values via attributes.

@mattwarren, what do you think?

[mattwarren]

You know what, I was thinking about this the other day, but only the gcConcurrent and gcServer settings. So yes, I think it's a good idea.

I guess you are thinking of adding them to [BenchmarkTask()], like the existing BenchmarkPlatform and BenchmarkJitVersion options?

[AndreyAkinshin]

We already have a lot of parameters in BenchmarkTask, it starts to look ugly. Maybe we can create another way to add new settings?

Yeah that's a good point

Maybe we can create another way to add new settings?

I'm not sure what is a good way to do it though?

I have just tried to rewrite LinqOptimizer project benchmarks to use BDN and failed because they were using <gcAllowVeryLargeObjects enabled="true" /> ;)

So there is a need for this feature ;)

@adamsitnik, am I right that now we can close this issue?

[adamsitnik]

@AndreyAkinshin gcAllowVeryLargeObjects is missing, I will add it right away
