This patch implements the 'loop' construct AST, as well as the basic appertainment rule. Additionally, it sets up the 'parent' compute construct, which is necessary for codegen/other diagnostics. A 'loop' can apply to a for or range-for loop, otherwise it has no other restrictions (though some of its clauses do).
