Review Mojo's priorities

• I have read the roadmap and priorities and I believe this request falls within the priorities.

What is your request?

An option in the compiler that prohibits the use of the standard library (---no-standard-library, or another name). The standard library makes calls to the operating system and that doesn't make sense when there isn't an operating system yet. Because this, for example, functions like print need to be written from scratch.

What is your motivation for this change?

Create a tiny operating system in Mojo as described here.

Any other details?
