Search stopped returning results for System.Console and other .NET APIs

[waf]

This is specifically involving the implementation of SourceBrowser on https://source.dot.net. I hope this is the correct repository.

It appears that search results recently degraded; a week or two ago I was able to find results for System.Console, System.DateTime, etc, as well as member searches like System.Console.WriteLine. Now, none of those return results.

Here's the HTTP request issued by source.dot.net's front-end code (captured by Firefox's web development tools):

Further examples are available on the source.dot.net "overview" page -- the first couple of hyperlinks on that page don't show results.

Thanks for creating this great tool—I love it and use it often.

The runtime assemblies are just... not getting indexed at all. The binlog reader isn't finding the compiler invocations somehow.... again...

dotnet/arcade#7520 should fix things once it gets into runtime.

This is now fixed.
