In this commit: * Change the lit_int_unsuffixed AST node to not carry a type, since it doesn't need one * Don't print "(unsuffixed)" when pretty-printing unsuffixed integer literals * Just print "I" instead of "(integral)" for integral type variables * Set up trans to use the information that will be gathered during typeck to construct the appropriate constants for unsuffixed int literals * Add logic for handling int_ty_sets in typeck::infer * Clean up unnecessary code in typeck::infer * Add missing mk_ functions to middle::ty * Add ty_var_integral to a few of the type utility functions it was missing from in middle::ty
