Bugfix expansion: return-from, sys:abscond-from, block*.
These three forms are not being traversed properly by the
macro expander.
* eval.c (do_expand): Do not treat return-from,
sys:abscond-from and block* in the same case as block.
block* evaluates all of its forms and so can just be walked
as a function call in the fallback case. The other two
must be in their own case because we must not use
expand_progn on them; they do not evaluate a progn-like
list of forms. This leads to inappropriate optimizations
like (return-from x (progn a b c)) -> (return-from x a b c).
