* encode future-generators as a domain containing the tupled upvars * follow opaque type aliases in `most_generic_ty` to treat them as the same as the type they point to in the encoding * add empty dummy domains for types that are pulled in, but are not supported yet
* create new aggregate caster to cast future-generator constructor arguments * encode future-generator constructor calls (analogous to ADTs but tupling up arguments) * encode references to dummy variables
* mangle additional characters ('{' '}', '#') appearing in
future-generator names
* mangle type parameter names, which may be necessary for those
generated by the compiler (e.g. "<resume_ty>")
* resolve calls to `IntoFuture::into_future` in order to obtain precise type information * replace calls to `Future::poll` by goto for now (for testing)

This draft adds some experimental capabilities to encode async functions as well as additional ways of annotating async functions and suspension points.
Given that encoding async code relies on some parts of the language that are not yet supported by the other encoder parts, this encodes some constructs as dummies in order to produce its encoding. Therefore, the resulting output requires some manual patching in order to verify the original code.
