Opal::Compiler#returns

The last sexps in method bodies, for example, need to be returned
in the compiled javascript. Due to syntax differences between
javascript any ruby, some sexps need to be handled specially. For
example, `if` statemented cannot be returned in javascript, so
instead the "truthy" and "falsy" parts of the if statement both
need to be returned instead.

Sexps that need to be returned are passed to this method, and the
alterned/new sexps are returned and should be used instead. Most
sexps can just be added into a `s(:return) sexp`, so that is the
default action if no special case is required.
