199c7e365c var ordering (#618 )

Propose the decision from #542, noting implementation from #563

Also integrates some of #339 into `variables.md` because that's actually how this started, looking for a proposal reference for #542

Control flow

Overview

Blocks of statements are generally executed linearly. However, statements are the primary place where this flow of execution can be controlled.

Carbon's flow control statements are:

if and else provides conditional execution of statements.
Loops:
- while executes the loop body for as long as the loop expression returns True.
- for iterates over an object, such as elements in an array.
- break exits loops.
- continue goes to the next iteration of a loop.
return ends the flow of execution within a function, returning it to the caller.
