Add more messages for assertion failures

[ChrisThrasher]

It's very user friendly to provide some explanation for why a compiletime or runtime assertion failed.

[ChrisThrasher]

I prefix uses of assert with the name of the function since at runtime it may not be obvious where the assertion failed. These strings make it easier to narrow down on exactly what API is being misused.
