Subject: Do loop fix (#209)

* Bug fix: emit logic for `do` loops

This case was never tested, and I was outputting some garbage characters. This comit fixes the codegen and adds a test case.

* Bug fix: make sure to pass through `[allow_uav_condition]`

This also fixes the standard library definition of `IncrementCounter()` so that it returns a `uint` instead of `void`.
