annotate-inlinable-defs

[arrdem]

This pass will traverse all defs in the AST after doing taken as value analysis and arity shaking to identify functions which are never taken as values, which are not part of the user defined API and which are constant and annotate them as ^:inline so that the emitter will inline their uses.

It's worth discussing the generality of this approach since there may be other things which can be inlined away but we'll start here.

This is blocked on #6 which is today's project.

note that for clojure core :inline isn't a bool, it's a macro function. This is silly and unfortunate, but it's the case. See TODO.org for notes on a better partial evaluation based implementation.
